    Hay,

    I’m struggling with a problem for an assignment, it states:

    "A MOSFET is used in a single-ended chopper circuit with an inductive load."

    No circuit diagram is provided! Think I can tackle the rest of the problem, but any ideas on how to draw the circuit? :)

    Hello Bertus and thanks for the link. I will just leave out the flywheel and go with that. :)

    Cheers Al.

    If you don't put the freewheeling diode in the circuit the back EMF of the motor when the MOSFET switches off will destroy the MOSFET and maybe the PWM circuit too.
