I am powering a half bridge with IRF740 MOSFETS using an IR2111 driver. The input voltage needs to get up to 200 V, but there is significant spiking in the voltage at the high side gate driver. The spiking get worse as I turn the voltage up. At about 40 V the voltage spike goes up to 110 V. If I turn the voltage up any higher than about 60 V the MOSFETS will blow up. Is there some sort of snubber configuration I could use?
