The initial goal for the project was to make a powerful 12 to 220 converter. The main advantage of this device is its ease of assembly, made by a push-pull circuit. Only 2 field effect transistors, without any master oscillators. Even if you have experience in a business such as assembling a converter, but there is a great desire to try, then there is nothing complicated in it, you can collect it without difficulty do it yourself.
It is not necessary to buy any parts for the device, all components can be found at home in the old technique.
Let's watch the video converter:
Regarding the parameters of the converter, unfortunately, the output frequency is variable, but you can easily turn it into direct current by installing a rectifier and a large capacitor with an estimated capacity of about 100 microfarads at a voltage of 400 volts. The operating frequency depends on the LC circuit. As a coil, we have the primary winding of the coil. Installed 2 chokes. The winding does not have a tap.
Power channel high-voltage channel transistors are used as power switches. They can be replaced with any low voltage. Power primarily depends on the transformer and yellow transistors.
As for the circuit, it will allow you to remove up to 500 watts or half a kilowatt of output power, while there will be no master circuits and other designs.
In addition to the transistor, zener diodes are also installed on the generator board to stabilize the gate voltage. The shutter limiter is also available at 470 OM; for construction, from 100 to 670 OM can be used.
In addition, 2 diodes are installed.
When using one common heat sink, they must be insulated without fail with gaskets and insulating washers.
It will overheat a bit, a choke, so you need to wrap it with a wire with a diameter of up to 2 mm.
The transformer used a finished 220 volt with a primary winding. The winding consists of 8 turns of thick wire.
The scheme can be without a midpoint or with a midpoint.
In our case, an incandescent lamp of 11 watts is connected. We need to light it up completely.
From DC, you can power all of the above devices. Do not power the refrigerator, vacuum cleaner, microwave. You can charge the battery from a phone, laptop and even a computer.
