Many years ago, I designed a PWM controller for a DC motor, using MOSFET transistors for the output. It was designed for a 12 volt trolling motor system system but the current capability was around 50 amps. It has served me well for more than 30 years, requiring only a replacement of the control potentiometer and of the MOSFET's when I accidentally reversed the power supply voltage once.
It could easily be modified to handle much higher voltages by simply choosing different MOSFET transistors. It was drawn up on paper (no computer back then) but I should still have the schematic around somewhere.
