Hi guys how are you?, I am working in a drive dc motor prototype. I am using the IRFP250MPbF MOSFET and IR2110 for gate control. I attached a picture of the circuit.





The H bridge circuit has had problems with the snubber circuits. I would like to help me calculate an appropriate snubber circuit.

I'm also trying to simulate the circuit in PSPICE, but I have problems with the IR2110 circuit.

The characteristics of switching are:

PWM to 40 kHz, it is implemented in a development board FPGA.

The characteristics of DC Motor are:

Continuous stall current 21 Amps

Peak current 92 Amps

Rated speed 3000 rpm

Thanks,
