    Why mosfet is less switching losses and more conduction losses..

    hello every one

    why mosfet is less switching losses and more conduction losses..
    and why Bjt is more switching losses

    any one can explain

    MOSFET basically has faster switching time than BJT,thus, less switching loss. A mosfet can have extremely low conduction loss.

    BJTs need a Baker clamp to make them switch quickly.
    As Barry said, the "overlap" time of current and voltage at the swithcing transition, can be much less for a mosfet. That isnt to say that there arent some special BJTs that can have special drive circuits to make them almost comparable....but its more hassle.
