I'm making a bi-directional back-to-back nFet switch to drive an AC motor, as shown in the following circuit.
I'm not worried about the driver since I've already built one based on a design posted by @JDT (btw, thanks man!) and it works wonderfully on a resistive load.
Anyway, I've placed a TVS diode across the mosfets to protect them a bit.
My question is this, I'm very much aware that motors demand up to 10 times more amps at startup (perhaps even more) than their normal rating. Is there any way to protect the fets from this surge, other than having to buy enormously oversized fets for this application?
