how to make a simple 4200W inverter, sine wave, 4 mosfet, IRF3205, jlcpcb

-Description: Make an inverter: A project that we have wanted to do for a long time, powering mains devices just with a battery, very impressive! We had never succeeded (by using logic and not by using a version created by a third party, that's where the interest lies, using electronic logic to manufacture complex devices as easily as possible ).

The key to operation and unfortunately the most difficult "part" to find via recovery is the use of a transformer with two secondaries (or two primaries depending on the direction in which it is used) which are both of the same ratio (1 for 1) and in reverse (if we put an equal alternating current in each of them it would cancel out...). We can therefore put positive currents of the type "cos²x" and "-cos²x" in turn, easy to create with an oscillator in the primaries so that the secondary coil increases their voltage and transforms them into a sinusoidal current... (greater than 0 when it comes from a "cos²x" and less than 0 when it comes from a "-cos²x"

In this video we present to you a rather finished version of our inverter to test it on different devices, and it works really well! unlike the Dynamo 230 Volts which was our first attempt at an inverter, this project is compatible with all devices consuming 30 Watts or less, that's actually not bad, incandescent bulbs, several economical bulbs at the same time, stereo fi! Laptop (direct powered), all transformers...

For once we have focused the video on a very explicit second part where we do not just give you our diagram but where we explain to you how our inverter works step by step to help you build it, understand how a oscillator (to make it, go to one of our old videos), the role of transistors and their logical operation then the transformer. The biggest difficulty for you will be to obtain the components^^ a word of advice, the older the devices, the better they are "equipped" with components useful to us (cathode ray tubes, video recorders, etc.)
