l6384
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 be a reason for burning.
Can someone post working circuit of L6384 or DC motor control circuit, 200V, 10A
I attach the circuit and the PCB of my masterpiece.
