    You are working very hard. V3 ckt shown above shows me that you have focused on making product not good productWhy u use ready made 12v to 5v buck? Use lm2576.Why no resistor between gate source of mosfet? It may burn out due to esd charging or floating cap charging.Why UF4007? Not shottky?Why snubber across inductor?Not lower mosfet Q3?How you choose these values. Have you calculated or seen results on scope? Or just copy and paste.Inductor value must be twise as per calculated. Inductance reduces as current increase.Why mosfet driver is away from mosfets? Poor placement. Place driver ground as close to bottom mosfet q4 source. Read placement of driver for mosfet more.Why do you need load driver? What on earth do you think will work on +12v when each equipment will work on 220V? Dont w...see more »You are working very hard.

What on earth do you think will work on +12v when each equipment will work on 220V? Dont waste time on illogical things.Dont suggest to remove tvs and mov in any case. It is needed as much as your rest circuit.Use 2E resistor between gate of mosfet and driver IC.Study is necessory for anything/everything. Pleae study.
