Pulse converting sinusoidal voltage 220v 10kW. The need for pure sine wave inverter circuits

• Additional filter

Rozrobkoyu circuits of the inverter pure sinusoid occupied not only a lot of people's minds, but also science and technology centers. inverters or blocks uninterrupted life, gaining popularity with the development of computer technology Trouble in software security, the loss of information during the raptomatic inclusion of life was hampered by the necessary security calls. The first outbuildings saw a pulsed voltage of a rectangular shape - a meander. The stench took care of a small gap of an hour, by stretching which it was possible to save the information that vikonat the staff of the computer. Further developments made it possible to create a thorough model of transformations.

The increase in the capacity of the batteries, the nominal intensity of the inverters made it possible to increase the hour of the work of computers, and to stop the DBZh to work with other attachments and accessories in case of interruptions in the power supply.

The first completion of the operation by showing that the robot was in possession of impulse voltage to produce up to an accelerated wear and tear of that technical equipment. Pevnі categorії obladnannya appeared not zdatnym pratsyuvati on pruzі, scho vіdіznyаєє іnі sinusoidy. The tightness of the zherel zhivlennya did not allow the connection of a sprat of outbuildings at once.

Vinyl demand in inverters with a sinusoidal form of voltage, building vitrimatization in kilka kilowatts. A partial solution to the problem was found. The virobniki chanted the transformation from the quasi-sinus. Such a form is sinusoidal, which is formed from impersonal small gatherings.

Natural that piece sinusoid

1. Scheme of life of a reworker.

The sinusoidal form of the voltage, which is vibrated by industrial generators, is created by wrapping the poles of the magnetic field. The robot of the electric motors is based on the combined electric energy of the magnetic field, which is wrapped around for injection on the rotor. With the shape of the voltage, which is blown in the form of a sinusoid, the rotor wrapper will be uneven, with speeding up or uplifting, which will appear on the technical station of the engine and the working part.

Vikoristannya napruzha created by the form until it has passed enough tests in practice, it is not necessary to vikoristovuvat yoga for the life of an expensive possession without the guarantees of a virobnik. The majority of the BDZH is recognized for supporting the basic life of the necessary functions.

Merezhevy is a strain, which is the source of the ideal shape. Moving and lowering transformer stations, see different possessing, scho zhivaє, create songs change the form mesh tension. More importantly, the choice of inductive navantage without compensating capacitor installations creates a number of phases, which infuse into the shape of the sinusoid. Massive connection of pulse blocks of life also works its part of creation, regardless of the presence of filters.

Figure 2. Installed at the outlet of the filter.

Otrimati pure sine when vikoristannі radio-electronic components dosit smoothly. The decision to lie on the surface. A straight-cut impulse in a simple file is composed of a harmonic series of sinusoids, the first of which is the frequency of impulses. It is not necessary to install an external filter at the exit.

The efficiency of operation of such an attachment is low. Significant part of the energy is absorbed by the elements of the filter and is converted into heat. The vaga and dimensions of the expansion are changing significantly. Seeing and vikoristovuvati filtered energy for charging is also hard to do. The scheme will significantly become more complicated, the growth of її variability, the superficiality will change.

Most of the experimenters agree on the idea that the modified sinusoid is entirely acceptable for most industrial and industrial attachments, accessories.

Turn to hell

Pure sine inverter circuit

Zhivlennya peretvoryuvach (mal. 1) can be dzherel with a folding form of tension or a constant struma. If the battery is different, filter F and diode M can not be installed. For the operation of the low-voltage part of the circuit, there is a place M1, selections on low-voltage diodes. It’s hard to finish such a scheme with a hand. The vikonavets is guilty of the mother singing dosvіd vykonanny robіbnih robit.

Figure 3. Coil connection with a voltage of 220 V.

The scheme works in this way. Set the generator on the D5 microcircuit to create a sinusoidal signal with a frequency of 50 Hz. Yogo scheme is a modified version of the Wine generator. Changes made to increase the reliability of the circuit and change the energy savings. Controllers D1, D2 modulate a sinusoidal signal. For modulation on microcircuits, there are different inputs: direct and inverting. Therefore, one side is launched for positive praise, the other - for negative. From the controller, the output signal is to be placed on the microcircuits D3, D4, which form the signal for switching by transistors.

The power part is chosen for the principle of brukivka. The voltage is connected to one diagonal of the bridge, the voltage of life is connected to another. When passing through one of the first periods, the strum passes through the minus terminal through VT4, winding L1, voltage, VT1, positive terminal of the jet. With a different pressure period, transistors VT2, VT3 work.

The protection for moving the maximum allowable struma is selected on resistors R17-19, R22 and diodes VD11,12. When the voltage drop on the resistors is overridden, the power switch has a difference on the output contacts D1, D2 and the circuit is attached to the robot.

Vyrivishiv dedicate the article to the preparation of DC AC power shifting the voltage to 220V. It’s very far away to see those bright spotlights and lamps, but it’s also a mobile life that is widely stagnant at home and in a car

Choice options

Use 3 optimal ways to prepare an inverter 12 to 220 with your own hands:

1. selection from ready-made blocks or radio constructors;
2. prepared from the dzherel of uninterrupted life;
3. selection of amateur radio schemes.

The Chinese can find good radio designers and ready-made blocks for choosing the conversion of a constant stream into a replacement 220V. For the price, this way will be the most costly, but it will take at least an hour.

Another way to upgrade the dzherel uninterrupted life (DBZH), which without a battery is sold in large quantities on Avito and cost from 100 to 300 rubles.

The most folded option for picking from scratch, you can’t do without a radioamator’s certificate. Come and prepare the cost, pay, pick up the components, work and even richer.

The design of the voltage changer

Let's take a look at the design of the sizable voltage changer that moves it from 12 to 220. The principle of operation for all current inverters will be the same. The high-frequency PWM controller sets the operating mode, frequency and amplitude. Vikonan's power part tight transistors, heat from which the building will be built.

A protector was installed at the entrance, which protects the short hum car battery. Instructed by transistors to attach a thermal sensor, which follows for their heating. At the time of overheating of the inverter 12-220V, the active cooling system is switched on, which consists of one or two fans. In budget models, the fan can be used regularly, and not more for high demand.

Power transistors at the output

sinusoid

Output signal shape car inverter rahunok high-frequency generator is formed. Sinusoid can be of two types:

1. modified sinusoid;
2. pure sinusoid, pure sine.

Non-leather electrical attachment can be used with a modified sinusoid, as it can be a rectangular shape. For some components, the operation mode changes, the stench can heat up and almost scribble. Podіbne can be taken away, like dimuvati light one lamp, as it may be, the quality is not regulated. A crackle and a flash begin.

Expensive DC AC, which shifts the voltages 12v 220v to produce a pure sine at the output. Koshtuyut richly more expensive, but the electric fit miraculously work with him.

An example of the stuffing peretvoryuvach

Storage with DBZH

If you don’t find anything to blame, don’t buy ready-made modules, you can try the computer for uninterrupted life, shortly IPL. The stench is 300-600W. I have Ippon for 6 sockets, 2 monitors, 1 system unit, 1 TV set, 3 warning cameras, video warning control system. Periodically, I switch to the working mode with the inclusion of a battery of 220, so that the battery is discharged, otherwise the term of service will be greatly shortened.

Colleagues of the electrician plugged in the best car acid battery to a trouble-free one, miraculously worked without interruption for 6 years, marveled at football in the country. In BDZh, a system for diagnosing a gel battery is sounded, as it indicates a low capacity. How to get to the car is impossible, even though the main water, the gel instead of acid.

Stuffing DBZH

The only problem is that the uninterrupted person may not be able to cut in the car while the engine is running. For the right radioamator, the problem is viable. It is possible to vicorate less when the engine is muffled.

Importantly, DBZH is recognized for short-hour work, if 220V sockets are known. When trivaly post-industrial robot put more active cooling. Ventilation is good for stationary version and for car inverter.

How and all accessories, wines are not transferred to the behavior when starting the engine with connections. The starter of the car strongly prosazhuє Volti, in the shortest time it starts to run out like when the battery goes out of tune. The biggest one will have haircuts at the output of 220V, a sinusoid will happen.

Storage of ready-made blocks

For folding a stationary or a car inverter 12v 220v, you can make ready-made blocks with your own hands, as they are sold on your own or from the Chinese. Tse spare an hour for the preparation of the payment, soldering that residual adjustment. It is enough to give them a body and darts with crocodiles.

You can also buy a radio constructor, which is equipped with a lot of radio components, it only needs soldering.

Orientation price for autumn 2016:

1. 300W - 400 rubles;
2. 500W - 700 rubles;
3. 1000W - 1500 rubles;
4. 2000W - 1700 rubles;
5. 3000W - 2500 rub.

For a joke on Aliexpress, please ask for an inverter 220 diy from a row of jokes. Shorthand "DIY" means "do-it-yourself folding".

Board for 500W, output for 160, 220, 380 volts

Radioconstructors

The radio constructor is cheaper, the board is ready. The available items can be already on the board. After folding, it is practically not necessary to adjust, for which an oscilloscope is necessary. Rozkid parametr_v radiocomponents and denominations badly chosen. Sometimes put spare parts in a bag, raptom through the lack of knowledge of the lower part.

Schemes of tight reversal

The push-pull inverter is important for the connection of everyday power tools at a daily dacha or fazendi. Low-power voltage changer for 500W and for 5000 - 10000 watts. power transistors at the exit. Therefore, the cost of preparation and the price are practically the same, transistors are inexpensive. For power, optimally 3000W, you can connect a drill, grinder and other tools.

I'll show you some schemes of inverters from 12, 24, 36 for 220V. So put in passenger car not recommended, you can vipadkovo zіpsuvati elektriku. Circuitry DC AC conversion 12 to 220 is simple, what sets the generator and the power part. The generator works on the popular TL494 and its analogues.

A lot of circuits for switching from 12v to 220v for cooking with your own hands can be known for the help
http://cxema.my1.ru/publ/istochniki_pitanija/preobrazovateli_naprjazhenija/101-4
There are close to 140 circuits there, half of them move the conversion from 12, 24 to 220V. Intensity from 50 to 5000W.

After folding, it is necessary to improve all the circuits for the help of an oscilloscope, it is necessary for mothers to work with high-voltage circuits.

To fold a 2500 watt power inverter, you need 16 transistors and 4 power transformers. The variability will be chimala, por_vnyanna іz the variant of a similar radio constructor. The advantage of such vitrates will be a pure sine at the output.

Converter 12/220V from sinus to output.

Peredmova.
Close to a month ago, I looked at the net for a simple conversion scheme 12 / 220v with a "clean" sine on the output and on my own, showing that it is not. Everything is sounding, it’s made, either by removing the pseudosine with a path of transformation without using a low-frequency moving transformer, or by turning it into a D-class power supply, by using a reference sinusoidal voltage. As a control device, that generation of sinusoids is encouraged to stop the microcontroller. Abo is given by the force of smartaps. Zagalom, it’s not easy to go out. I had a chance to spend a lot of time at the entrance, in order to expand the scheme, which would allow for greater simplicity and "purity" of the sinus.

Characteristics:
Input voltage 12...14V
Output voltage 50Hz 220+/-2V
Max power 50W
KKD 84...90%.

Robot.
Set the generator, the reference voltage and the comparator selected on DA2. The outer elements of DD1 and DD2 repeat the internal structure of TL494, in the third part low frequencies(False description of the D-trigger).
Dali for the help of the low-frequency filter, the upper harmonic warehouses of the ShІM are used. LPF is composed of two parts. Persha-DA1.1, LPF with smooth frequency response. The other one is DA1.2 notch filter with 150Hz choking frequency. The analysis shows that only the first and unpaired harmonics are hidden in PWM, so this filter is enough to form a "harmonic" sine (oscillogram 2). And the shards of the first harmonica are practically linearly deposited in the space, then we take good sine sine with an accurate constant warehouse, equal + 2.5V. Dali dodatkovo otrimuemo inverse sinusoid (vysnovok 14 DA1.4).
DA3, DA5, VT1, VT2 selects the first ULF channel to class D. Another channel is selective for DA4, DA7, VT3, VT4. At the output of the first and the other ULF channel, anti-phase sinusoids are formed (oscillogram 3).
From the output of the transformer through one place is supplied Zvorotniy zv'azok for output voltage. Such a rank output voltage stabilize.

Construction and details.
Transformer TV1 is an additional TP60-2 transformer, which was installed at the famous video recorder "Elektronika VM-12". From the transformer, all secondary windings are wound, and instead of them, one winding is wound, which covers 33 turns. winding dart with a diameter of 0.7 mm, folded in sim times. You can beat the middle tire, which goes beyond the area of ​​the cut. When a voltage of 220V is applied to the secondary (in the case of a switch, it is primary) windings of the transformer at idle, the voltage becomes 6.5V.
Throttles L1 and L2 are wound on ferrite rings with a size of 24 * 13 * 9.7 mm and 22 turns of winding drota with a diameter of 1.5 mm. Unfortunately, the brand and magnetic penetration of these ferite rings are not known to me. The stench vikoristovuyut at the second lansyugs of pulsed computer blocks of life of the ATX type.
Transistors and driver chips DA5, DA7 can be found on motherboards.
All transistors are installed on one radiator with an area of ​​15...20 cm2. Mica gaskets are used for external insulation of the radiator.
Capacitors C21 ... C24 type K73-17 for a voltage of 63V.
Capacitor C25 type K73-17 for 630V.
Diodi can be twisted, whether it be, with a maximum turning voltage of at least 400V.
Resistors R44, R45 are less than 0.25W.

Nashtuvannya.
1. Remove the primary winding of the transformer.
2. With the resistor R9, set the pulse frequency of 100 Hz at the output DA2 (oscillogram 1).
3. Verify the presence of a sinusoidal signal (oscillogram 2) on vertices 7 and 14 DA1. The signals may be but opposite phases, but the same for the form.
4. Resistors R22 and R31 insert a signal at the output of the first channel of the ULF along with the oscillogram 3. Also with another channel (R24 and R34).
5. Insert a ruhomy contact of the resistor R4 at the top behind the position diagram.
6. Connect to the exit reworking the equivalent of the vanity. It is possible to vicorate the lamp to heat the lamp at a pressure of 25W.
7. Connect the primary winding of the transformer.
8. With resistor R4, set a voltage of 220 at the output of the switch.

P.S.
On my scheme, it is easy to scale up in order to reduce tightness. At the principle, the scheme, with additional extensions, is attached to the selection of other outgoing frequencies. For example, 60Hz or 400Hz.
KKD, it is possible to increase the troch, in order to replace the throttles L1 and L2 more tightening.

How do you like the article?

When vikoristannі low-pressure butt fittings often blamed on the need for a converting voltage from 12 to 220 volts. You can also have a laptop, charger mobile phone or a tablet, and navigate a TV set on LED elements.

1. three accidents of centralized energy supply;
2. Emergency power supply of electronics gas boiler;
3. Vіdsutnіst pobutovoї merezhі 220 volts garden plot, garage cooperative);
4. Car;
5. Tourist parking (for availability, take a 12 volt battery with you).

In all of these modes, the battery is sufficient for charging, and you can fully charge the electricity supply. Important! The tension of the tension of the fitting is not guilty of overhaving a sprat of hundreds of watts. Bigger pressure to put the battery in, which vikoristovuєtsya like a donor.

For the sake of justice, it is significant that life blocks and chargers are installed in a car for a car, which are connected to side railings 12 volts. The vikonans stink at the sight of the rose, which is plugged into the socket of the cigarette lighter.

However, even though you have a small number of gadgets, you will have to grow up to buy such a large number of chargers. And if you change one switch from 12 to 220, you will ensure the complete universality of the connection.

For sale there is a great assortment of ready-made converts.

The intensity varies from 150 W to a few kilowatts. Understandably, skin tightness is relieved by the need to take a water battery. It is also necessary to respectfully read technical characteristics- Often, for advertising purposes, vibrators show peak tightness on the packaging, as if turning over only a few seconds. Working tension is usually 25% - 30% lower.

Changes of converting 12 to 220 volts

For the right choice, be aware of the main types of voltage conversion, presented on the market of electrical goods:

Behind the shape of the output voltage signal

Attachments are subdivided into pure sine and modified sine. The difference in the visual signal can be seen in the illustration.

On the right, in what transforms work wrong, like generators snake struma. Served at the entrance to the annex constant strum song size.

The lower part of the wine is converted to pulse (for the safety of the robotic moving transformer), then from the removed pulsed stream a sinusoidal curve is formed, which is equal to the greater variable voltage of 220 volts. To create a smooth curve, a road scheme is needed, and more pickers try to prop up buyers for an economical price.

Charging outbuildings and blocks of life for laptops have been modified and the curve has been modified. And the sound-activating equipment can work with interruptions and strong shifts. Active blocks of life, for example, in LED TVs, get very hot for such an input signal.

Є vipadki exit from the exploitation of blocks of living. Attachments with electric motors (for example, a refrigerator compressor or a gas boiler pump) can also work with failures when connected to a conversion with a modified sinus.

For the implementation of the functions. Ways to take changing voltageіz postіynogo dosit rich. Let's look at the main ones:

Transformer attachments

May be satisfied with the primitive, but with the help of an effective design. The simplest turner, which you can pick with a hand.

For the help of a multivibrator, the constant stream is transformed into an impulse one, with a frequency of 50 Hz. Then we move the transformer to change the voltage equal to 220 volts, a stabilizer is mounted on the output.

The shortcoming of such a layout is the great expansion and the impossibility of taking a pure sine. Ale for the simplest tasks (robot charger outbuilding or a soldering iron) is good enough. Golovne zavdannya, as it is necessary to virishiti, - how to wind a transformer for a turnaround. Pіdіyde torоїdalny serdya (for compactness) vіd bіl-yаkogo nepotіbіbnі block zhivlennja.

I understood secondary winding Vitkіv may be more in vіdpovіdnіst up to the coefficient of advancement. The intensity of such outbuildings does not exceed 200 watts.

The offensive type of conversion is on the generator, what is set. Sound for these purposes, the microcircuit KR1211EU1 is played. head detail peretvoryuvacha vіtchiznyany virobnitstv, її varіst not high. After that, how to set the generator to change the voltage - a signal to go on the key, switch on the IRL2505 transistors.

Next, a moving transformer is connected, at the output of which a changeable voltage of 220 volts is formed. To reduce the injection of high-frequency impulses, which are often used on the secondary winding - installing an important capacitor.

The turn-over pressure can reach 500 W directly from the transformer. It is selected from a reserve, which exceeds the face value by 2.5 times. The focus on other elements is not so high. For example, in case of exhaustion, which does not exceed the value of 200 W, the key transistors work without radiators.

The layout of the flooring is far away, so that you can plant a lot of pickers at the craftsmen. And the availability of the elemental base allows you to change your mind from 12 to 220 with your own hands.

More perfected from a technical point of view є reworking on PWM controllers. Such attachments at the output give a pure sine, and so can a high KKD.

The completed scheme allows you to create an exhausting outbuilding (1-2 kW) for a remarkably compact size. The dimensions are determined by the cooling radiators and the ventilation system. High variability of the elemental base

However, in pairs with promissory words, savings in case of independent choice of sutteva. Such a changeover will tighten and eat the refrigerator. And the yakіsna form of the output signal allows you to connect the powerfully quiet - TVs and music centers.

Important! It should not be forgotten that the temple was exhausted, changing the vimagatime of a lot of the primary source of electricity. For trial operation with a voltage of 800-1000V, battery for battery may be not less than 100 a/year.

However, compact outbuildings, designated for living smaller gadgets, are still the most popular. The 12220 conversion circuit on transistors is available to a skin radioamator, who has a soldering iron in his hands.

Having chosen such a circuit in a neat case, you can install it in a car, and you will have a right 220 volt socket.

The most self-confident reworker:
As you have a computer block of uninterrupted life, the battery has been punished for a long time, you have a miracle donor for creation autonomous dzherel 220 volt. The shifter from the bezperebіynik practically does not vimagaє vruchannya from the side.

Sufficiently plug in a drained battery (for example, a car battery) and turn the switch ready.
Having read our material, you can not only choose the one suitable for the store, but also work it out on your own.
