I have built a half bridge SMPS that outputs 110V at around 5A amps to power a CNC motor. It's based on SG3525 with a GDT. The power supply works fine under resistive loads (some light bulbs), there's no abnormal heating up of the components even after a long time under load, but when connecting the motor the transistors blow up after short time. There is soft start implemented.
Am I missing special considerations when driving these kind of loads?
