Additional FeaturesYou can congratulate me. Now I have made regenerative breaker that helps me to get regen on my SERIES DC motor. I left my PWM controller "as is". Just added a special galvanicaly insulated device that excites Field winding and helps the motor to become a generator. My EV recuperator consumes about 7A at 110V, and the motor gives about 40-50A of current back into the traction battery at the same.
