Power electronic switches VS dc contactor

  1. May 21, 2012 #1
    As we know the contactor in power circuit make spark when it open and so its contacts may damage and aging
    Is it possible to replaace the contactor by power electronics switches such as MOSFET TRIAC and IGBT?

    Any help will be appreciated

    The improperly selected semiconductor switch's junctions/fields can also be damaged.
