One Night Project: Analog Current-Mode Hysteresis Brushed Motor Controller

Hysteresis Best-Teresis. Tonight I built a current-mode controller for brushed motors. Instead of going the traditional route using a microcontroller controlling PWM through a PI loop, I used only a comparator and an op amp. I had a hunch that this would work while being exceedingly simple. My hunch turned out to be correct, and […]
