Question

Mention two advantages of power mosfet over power transistor

Answer 1

These are reasons why MOSFETs are preffered over Transistos

1•Lower switching losses (but higher conduction losses)

MOSFET are voltage control device: 2•providing a constant voltage is easier then constant current

3•Temperature coefficient postive temp coefficient of resistance so parallel operataion is easier then Transistor

4•Mosfet don’t have secondry breakdown problems like BTTs.
