I have fun. I’ve created this original design to serve as a reversible brushed DC motor controller, and have made provisions to allow it to also be useful as a single phase VFD or inverter. I’m reasonably confident that this design can utilize PWM frequencies of less than 50kHz for both the speed control (PWM_IN) and for reversing the current which is sufficient to permit use of this device as an inverter or a single phase VFD, with the potential for SPWM, as well.
