250 to 5000 watts PWM DC/AC 220V Power Inverter
Here's the picture of the board.
HelloI made the PCB from the picture of the backside, the one of the built board.I can't use TIP122 and I have to drive the 2N3773 directly from the board as the TIP122 burn the gates of the 2N3773 (they aplly 12V instead of 7V max gate voltage of the 2N3773).With this I can power a 20W bulb but voltage drops to 200V. I have a 600VA transformer and I get 12V by powering it from 220AC.I power it from a 10A power supply and current and voltage on it stay stable also under load.Can someone help me?I'll do the test by powering the transformer from the 12V side and also to connect a load on it in theese days.
HelloNice projectWould it be possible to have the pcb file of the board with Low voltage warning?Because it isn't downloadable.Giulio
