I made a motor controller using IR2113's as the h-bridge controllers. This circuit has been working fine and I have done a lot of testing on it. Normally I would turn off the PWM pulse before plugging in the 24V for the motor (the motor draws about 10 amps), but this time I forgot and ended up plugging in the motor when the PWM was at a maximum. Of course this caused the plug to spark as it made contact with the battery terminal, and the mosfets on my motor controller blew.
Is it likely (or possible) that the mosfets blew as a result of plugging in the motors' power supply when the PWM was on already? I have checked every other aspect of the circuit and cannot find a problem (and as I said, the controller has been working fine for a while before this happened)
