Hello, I am testing my second design with L4984D, the first one I designed work fine, but this second board breaks the FETs and I think that is due to overvoltage when I turn on the power. Could anyone tell me why that could be?Thanks

Hello, I designed and manufactured a PFC circuit with a L4984D for 400V 800W output. I tested it until 860W with a resistive load and function ok. I need to power with it a 600W, 400V to 24V DCDC. This second step consist of a full bridge with a tran...
