I am currently designing a motor controller for a SUMO robotics challenge.
Each of a two motor setup exhibits a (0.15-0.40) N.m torque resulting them pulling (35-70) Amps nominally and a peak of 120 Amps when stalled (this happens frequently).
The driver needs to be compact and relevantly small. (12x9) cm is kind of the maximum.
I am having trouble finding a good technical guide to designing a proper power mosfet H-bridge controller for the motors. I know all the theory needed but I need a guide that deals with all high current related issues.
