i am making a power mosfet chopper circuit and i am having some problem. i am using pwm to control it.
i have control speed of a 1.1 kwatt motor with it. The circuit works fine when i apply 5 volts an the control signal but as soon as i apply pwm the mosfet gets burns. I am apply a pwm of 4 kHz. it has to chop voltage from 320 vots dc to 130 volts dc.
plz see the attachments
