    Hello everyone,

    I've been mulling over an idea for an invention for a while now, and the only thing holding me back is how to switch between two high current (about 200 amps), 12v DC sources. I need the switch to reliably cycle at least 10,000 times, and as far as I know, mechanical switches aren't reliable/durable enough for this. I recently discovered IGBT switches, so I'm looking into those as a possibility. Does anyone have any suggestions for a switch type?

    MOSFETs are a better choice- IGBTs have too high of a saturation voltage.

    A bunch of them in parallel.

    There are plenty of MOSFETS that can switch that. Look up, mosfet on digikey.com and filter on current.

    Switching frequency may be an issure? Any details that can be shared?
