Hello!
I am attempting to build a solid state relay to replace a few mechanical relays in my car... The primary objective will be very little heat generated with no need for a heatsink to switch 20-30 amp loads. I believe this should be possible as many years ago I have seen this done...
I figure the best way to do this is with a Mosfet and a mosfet driver (for the best efficiency).
Could I get some advice on what the absolute best and most efficient mosfets are and the absolute best drivers. I want this thing to be rock solid reliable and generate very little heat. What would you use for the absolute best Mosfet High current switch?
Parameters:
Control voltage: 5 -12V (possibly driven from a microcontroller)
Switched on-off 12V 20-30 amps
