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,
