    I want to connect the Generator output with rectifier by using solid state switches instead of contactors
    its 1000V 100A output

    Is it possible to get such solid state relays or switches?
    will it cost less than mechanical contactor?

    While this is technically feasible, the logistics and cost of such tend to be prohibitive. For safety considerations, a mechanical switch or contactor is a far safer solution.

    IGBTs require heatsinks
    Requires (3) dual packs for 3 phase
    Requires isolated gate drive circuitry

    Check out Powerex for high voltage IGBT devices--they go up to 6.5kV (for a price)
