I am trying to build a full wave controlled rectifier for 1 HP 180v 5.5A DC motor.
Please guide me about how to proceed with design and how to choose which power device to use and what its rating should be?

Have a DC(pm type ) motor 180v, Full Load Current ~ 3A (1 HP)

When driving a small motor was OK but when using as above the MOSFET was destroyed.
Can anybody suggest a snubber ckt for the above combination. (...)
