Do-it-yourself inverter 12 at 220 pure sine

This self-contained miniature inverter of 12-220 volts, which is easy to grab from a light bulb cartridge, was victorious by the author ( Aka Kasyan) for drawing, de demonstrating the "generator of free electricity".

Back to top video with focus.

A 40 watt merezhe light bulb was vikoristovuvalsya.

This light bulb is really not simple, far into the small expanse of smell, the right voltage inverter is moving 12-220 volts, the building is living the light bulb in the outside voltage.

You can see 2 pole transistors. To finish the exhaustion 20-ampere field transistors taken from the inverter. The capacitor with the primary winding of the power transformer establishes the kolyavny circuit. Throttle on the plus side, winding on the ring energy-saving light bulbs. You can also see two basic intermediate resistors for 240 ohms and two ultra-wide diodes.

Throttle one 7 turns with a double wire 0.8 mm on the ring in the economy of the lamp. The core is from a Chinese electronic transformer 80 watts, the primary winding is 2 x 6 turns, the core wire is 0.8, the secondary winding is 0.3 mm 130-150 turns.

Scheme that folding converting 12 to 220 volts.

Let's take a look at the inverter circuit of a constant stream of 12 volts at 220 snake struma, yak bula is named Enigma. Bachimo has three different schemes on display. That is the main nodes, as they were in the design. The first in the lower part is the battery, so those that were in charger attachment. All two consecutively connected lithium-ion batteries line stabilizer type 7805, which type is required for charging mobile phone. Vіn buv vstanovleny on a small teplovidvіd. The pluses and minuses of the battery went without a hitch to the plug. Move from the stabilizer to the USB socket. When connected to a sub-zhuvach buv constant strum 12 volts from the battery.

At the top of the left part, there is a diagram, as if the LDS was built. This is a simple two-stroke voltage changeover that drives selections based on a simple multivibrator. Transistors IRF 630.

In addition, the plus in sequence is also a 2-watt resistor of 10 ohms, so that the transistors did not heat up superficially.

Two gate, intermediate resistors on R1, R2 per 1 com. High-voltage transformer for supplying LCD monitors. At the exit, the stench settles down to a voltage of about 3 kilovolts. When applied directly to the LDS, then the flask, the lamp lights up. You can contact me again for help with a small scheme.

The third scheme is the same as those found at the plinth. Є entrance zhivlennya - a plus. Plus go to the middle point of the transformer. Minus, the earth is hot as far as transistors. Plus, through a small inductance L1 is fed to the middle point of the transformer. Vin of insurance for a two-stroke inverter.

Vibration inverter based on the principle of resonant switching. At power lancers, a capacitor of 1 microfarad is connected in parallel. Bazhano vikoristovuvat plіvkovі polypropylene capacitors for 160, 250 or 400 volts. The capacitor and the primary winding of the transformer make up the kolyvalny circuit.

Transistor type 20n60, it is also recommended to switch high voltage transistors with a voltage of over 100 volts. Chim higher, Tim better. Tse polyovy n-channel transistors.

Masa sleepy, then go to the transistors. They gave two diodes d1 and d2 Ultra Fast, for example UF 4001 with a strum of 1 ampere with a return voltage of 1 kilovolt. So the very 2 gate resistors R3, R4 with a nominal value of 1 kilo-ohm. The intensity of the values ​​of the resistors is 0.25 W. Take a smaller bagzhano.

Winding transformer on the ring from the monitor. The primary winding is made up of two according to sim. Secondary winding 140-150 turns. The diameter of the core of the primary winding is 0.5 mm in parallel up to 5 wires. The secondary winding of the bula is wound with a single dart with a diameter of 0.3 mm.

The finished inverter does not require any charging. The transformer can be wound on a different core. You can open up the transformer. You can win also armored cups and in.

Regardless of the simplicity of the circuit, the intensity can reach 500 watts with a power transformer, a capacitor and a transistor in a lance. For example, the video archive of the photo archive demonstrates the layout of the scheme of this inverter.

About the inverter per kilowatt.

Inverters 12-220 Volts are necessary for the life of the equipment, as there is no possibility of increasing the supply of the butt line. I’ll add a special feature in what you can do for yoga with help constant voltage 12 In a change of 220 V. Literally a decade ago, such a thing was practically unacceptable, but today, if the elemental base is great, it doesn’t matter if such a transformation is possible.

Inverter pressure

Vikoristati car inverter 12-220 pіd hour more expensive. Whether it’s a well-made technique, it’s possible to practice it in the minds of the sexes. The axis of only the maximum admissible drive is small - a number of Watts. The most powerful accessories allow you to connect the power supply to a voltage of 2-3 kW, but battery for battery sit down shyly. Tipi navantagen іz spodzhivannya strumu:

1. Reactive - energy is often reduced, which is taken from the body of life.
2. Active - energy is reduced to the maximum.

As you know for sure, if you want to connect the switch to the inverter, then you will need to increase the maximum tension in the warehouse of great work. It is possible that you are planning to connect to the power supply with a maximum power of 300 watts. The intensity of the inverter itself can be approximately 25% greater - such a reserve is sufficient. Therefore, to satisfy the needs, an inverter with a power of 375 watts is required. Ale, you don’t know this for sale. That is why it is necessary to choose a power supply of 400 W - the closest one to the values.

Where can you vikoristovuvat tі pristroї?

The simplest type of voltage inverter is 12-220 Volt - it's the only thing that is used in computer technology. Ale stinks, there is one great nedolіk - the pressure is small, the battery is running out of time. And yet, in the future, there are attachments to the couple with a mini-electric power station (wind-type type), stable eating is safe. The inverter can sound in such designs:

1. Security alarms.
2. Cauldrons of fire.
3. Pump stations.
4. Computer servers and other systems.

In other words, the stench will stagnate there, where it is necessary to constantly reveal a lifeline of 220 volts. Pobutovі voltage stabilizers - nothing else, like an inverter. Only in them transform changing voltage at a postyne, stabilize, after which it rises up to 220 volts. Moreover, for the help of electric power switches and a PWM modulator, it is possible to reach a practically ideal sinusoid.

Features of the robotic design

Inverters 12-220 Volts are widely used. Peresіchnі avtomobilіlіst vikoristovuyut їх zherelo zherelo zhivlennya during distant trips. You can simply turn on an electric razor, hair dryer, TV, boil a kettle. It's true, it's quick to put the battery in. Therefore, it is better to vikoristovuvat add-ons for living with the first necessary lighting.

The simplest self-contained inverters 12-220 can be made from several power transistors and a multivibrator. The operation of the accessory can be worn out in severe frost. And the axis for sintering needs to be cooled down, otherwise the transistors will go out of tune. A simple cooler like a computer can be installed on a cooling radiator for power transistors.

The simplest self-contained inverter

May all the inverters, if they are for sale, work for the help of a high-frequency streamer. Classic schemes, yakі were prepared with the improvement of transformers, they were mostly forgotten, they were replaced by impulse structures.

On the basis of one K561TM2 microcircuit, which consists of two D-trigers, you can make the simplest tractor for the inverter. The circuit consists of a generator that sets the role of a vicon DD1, as well as a frequency dilator prepared on a trigger DD1.2.

Power transistors type KT827 and KT819 are used for voltage conversion. Better results show the field transistors type IRFZ44. For the help of the generator, which is set, a sinusoid vibrates, as is necessary for a normal robotic design.

Features of the inverter

To select the 50 Hz circuit, it is necessary to twist secondary winding and in parallel with it, electrolytic capacitors and an element of vanishing are connected with it. If the trip is not connected to the exit, the scheme does not work. As soon as you plug in a slower inverter, the inverter is more likely to change the voltage from 12 to 220 volts.

The sinusoid at the output is far from ideal. Tse majestic shortfall of a similar scheme. In order to increase the intensity of exhaustion, it is necessary to install more expensive and efficient types of transistors. Return respect for the electric capacitor, connections to the exit. Vіn is to blame for the cost of insurance for a minimum voltage of 250 V. If it is shorter, then the value will be greater than 300 V.

Outbuildings on modern elemental base

Such schemes can be vicorated for eating butt fittings, lamps daylight, etc. power transistors type KT819GM ​​are mounted on radiators with a large area to improve cooling. Scheme to avenge the generator, which is set, on the logical element KR121EU1, by analogy, like in the foreseen cascade, as well as the cascade. Pole transistors IRL2505 are badly processed.

Vybir on the microcircuit KR12116U1 fell not in the fall - in it there is a two-channel regulation of the power switches. That is ideal for simple constructions. Vіd pasivnyh elementіv, scho vikoristovuyutsya in lanceuge, deposit the frequency, how viroblyatima generator, scho set. For an additional signal from the generator, the sounding and fading of the conductors is carried out.

If the channels in the transistors are open, then the opir is only 0.008 Ohm - it's not enough. Also, you can beat transistors with little effort. For example, a transformer is installed at the output, which has a power of 100 W, transistors in normal mode will run a stream of about 104 A. In a pulsed mode, the value can add up to 350-360 Amperes.

Ready to pay for the selection of inverters

At the sale, you can use ready-made modules. Stink є pay, they have installed:

1. Transformers.
2. Napіvprovіdnikovі silovі keys.
3. Radiator.
4. Passive elements.
5. Attached zahisnogo inclusion, zabіzhniks.

You can see such an inverter 12 220 pure sine at the output, so it is made on a modern element base. The price of finished blocks is high. The least cost is no less than 300-350 rubles, and that is the wholesale price. Whatever I put in the fit, then the yoga varity fit in more.

And first of all, if you want to add such additions, you need to know the required building. The installation of the payment needs to be done in such a manner that it is good to cool off. Bazhano zrobiti dodatkovo primusov cooling behind the help of a cooler like a personal computer. Inverter 12-220, the scheme of which is built higher, so it can be installed in the upper case. Golovnya, so that they didn’t get to the high-voltage visnovkіv.

Uninterrupted friend of life!

If you have a “zayviy” bezperebіynik, which village has a battery, you can revive it. For whom it is necessary to work small changes:

1. Take away the old battery.
2. Solder new wires for connecting to a 12 Volt battery.
3. On the edges of the darts, install clamps for connecting with a car battery. If you want to be a vicarist in a car, you can get lively from a smoker. Ale, it’s so careless to fix it - I’ll build a great tension, calling out the heating of the wires above the world.

Schob connect to dzherel uninterrupted life by-butov technique you need to install sockets. The simplest of the old mesh filter and plugging the dart with a plug to make it transferable, all the equipment is turned on in the yak.

Features of the design on the basis of an uninterruptible

With a capacity of 55 A / year, a similar design can achieve a normal temperature in the incubator for 100 eggs, for example. Whether a farmer knows how terrible it is for incubators. The truth is, the pressure of such an accessory is small, an air conditioner or a refrigerator cannot work normally.

One shortfall in a similar design - standard scheme can't recharge car battery. Therefore, if the battery is low, it is necessary to put it on charge in the form of a normal outbuilding, which you see a stream over 5-6 Amperes.

Self-closing exhaust inverter

To prepare a 12v 220 3000W inverter with your own hands, you need to know the basics of electrical engineering, beginners in installation. Come prepare a sprig of specific elements. One of them is pulse transformer. With this help, a voltage increase from 12 to 220 volts is carried out. It is also necessary to acquire dekilkom with expensive elements. The stench is rehabilitated below:

1. PWM modulator. Necessary for robotic navprovidnikovyh keys. With this help, the frequency of the work of the whole scheme is determined. It is necessary to indicate that the frequency of switching power keys is a few dozen thousand times per second.
2. Napіvprovіdnikovі transistors, which work as a power switch, allow not only to strengthen the signal, but also to make commutation. The stench vibrates and curls, and in pairs with a PWM modulator, they create a practically pure sinusoid.
3. Aluminum radiators from a large surface area. I’ll add more pressure, tim large area radiator is needed.
4. Foil material, on which the installation of all elements is designed. For bazhannya, obviously, you can visconat the overhead installation, but if you borrow more than a lot of money. Such self-contained inverter 12-220 with your own hands you can work for a sprat of khvilin, but it will not be safe to fawn on him, so you won’t get used to entering.
5. Passive elements - resistors, capacitors.
6. Z'ednuvalni darts.

When preparing an attachment, you may need a piece of electromagnetic relays for switching. To the point, it is possible to prove that the replacement of power keys is an acceptable choice of simple electromagnetic relays. Only one ale - switching speed is too high (40-60 ths. spratsovuvan per second). Therefore, electromechanical attachments cannot cope with such tasks.

Ready inverters

If you don’t need to work an inverter 12 v 220 3000 W with your own hands, you can bring a ready-made version at the fire building, with a rose for connecting accessories. Ale cina already bites too much. Found, the power of some kind of ice is 50 W, you can buy for 800-1000 rubles. І stitch yogo maximum for charging a laptop battery or a life cycle light-one lamps lighting. Do not connect an electric hair dryer or a curling iron to such an attachment.

Larger exhaust outbuildings (more than 2000 W) may have a reasonable price. The found inverter 12-220 will cost 3000-5000 rubles. Ale lay everything in the virobnik. Yakіsnі, richly functional prilady vіrobnitstv vіdomih firms can cost over 20,000 rubles. For this very reason, people who are more or less familiar with electrical engineering will be able to work the inverter 12-220 with their own hands. The benefit of the elements for cooking can be known in the simple block life of a personal computer

In our time, at the skin in the state, or in easy access, for an hour, blocks of life from the computer are not needed, just lie down, crouch with a saw and occupy the space. And maybe the stench burned up, but it’s not important, even if it’s necessary, take more deaky elements. Picking up the fee of such a conversion (). And having done it again, one more time, to that the radio components were, and the fee was already prepared if the loan was already prepared. Chip zastosovuvav new - from the store, but sometimes similar analogs to put at the ATX living blocks themselves.

Transformer of small size - from the block 250 watts. Transistors taken from stock - 44N poles, so absolutely new.

Known aluminum radiator, screwing transistors through plugs and pads, smearing them with good thermal paste.

The circuit of the 12-220 voltage switch was wound up, life was supplied from the battery 12 volts 7 a / year, on the terminals of which, with a fresh charge, it was close to 13 volts. Yak navantazhennya (under such tension and was chosen approximately) - a light bulb of 60 watts at 220 volts, it does not shine at all, but it’s still good.

The radiator is out of stock - 2 mm aluminium, heat input is good. After the first few years of work, the field transistors heated up to 40 degrees! The flow rate is approximately 2.7 amperes per battery, the robot is stable without damage and overheating, and the transformer axis is weak and warm (although it is visible and does not burn anything) such a change, or you can put more active cooling near the fan, even if the transistors show significantly more power and more low power, so with such a radiator you can stretch 200 watts.

The scheme of converting 12-220 is simple to repeat, when folded exactly in face value, when you pay, you pay in a day.

Video

The video of the robotic circuit shows the strum that flows through the lances, and the 60 watt lamp works. Before speech, the darts at the D832 multimeter with such a strum for the first time were kinder. If you put a larger transformer, then expand the other one, otherwise it’s not possible to get a larger transformer near the dimensions, and let everything go out with a small one.

For lovers of miniaturization, it’s wonderfully good, but if you let the transformer go to the transistors, in practice it’s less than 1 cm, and the stench with its warmth trohi warms up and the transformer is already warm, it’s better for a couple of centimeters to put in the keys and in the board a couple of openings for the ventilation flow povіtrya from the bottom of the hill.
