I'm using H-bridge with IRF740 (MOSFET) to convert 315VDC to 230VAC. But the upper mosfets are frequently get damage within few seconds. I can't find what is the problem. Help me...
I don't see a reasonable way.if I replace the transistors/mosfets with HV ratings, then?
The key specification can be found on the very first lines of the datasheet, titled "Features".datasheet of IR2110 says that the IC have to run at 15V Vcc, but I'm working with 12V Vcc and logic TTL. so how can I use IR2110?
Gate drive supply range from 10 to 20V
5V is actually better for low delay.3.3V logic compatible
many many thanks to RCinFLA. I've got this circuit in a China product, 600W/12V inverter. I was trying to find out the schematic diagram from their product.

I can't understand the function of D6 & D7. can you explain? this circuit is for 155V, my one is 315V.
