I built a scheme that controls the speed of DC motor through the PC, see the circuit. Everything was fine with power supply of the motor up to 30V. When I applied 200V everything burned. I didn't understand what happened - the two MOSFETs IRFP260N, the MOSFET driver L6384 and the uC are out of order.
I didn't apply a load but this couldn't (...)
