The image below is the H-bridge that i have design and make out.
This h-bridge is a 24V and use to drive a DC brush motor which is 24V, 150W. After i test it, the driver can work but when i switch the direction, the lower part N-mosfet will burn. Because of this, I want to include snubber circuit to protect my mosfet and the motor but i don't know how to design it. Is the RC snubber is suitable or the RCD snubber is suitable And how to calculate the value of R,C and/D?
Can anyone help ? What actually parameter that i have to find to design the snubber circuit?
