Nicely done. I appreciate the creative use of slides on what is a detailed subject. Please do more! Specifically I would love to know the impact of overvoltage on series wound DC motors for EV conversions.
Yes, anything that large would be custom made, normally. What most companies do is use several FETs in parallel, that way they can share the current. So if you use 5 100A FETs in parallel you essentially have 500A capacity.
