Hi, I am currently working on a project that compares the regen braking of DC and AC motors. The DC circuit was fairly simple so I finished it pretty quickly. However, I am quite stuck on the AC circuit design. After doing some research, I learned that decreasing the frequency fed into the induction motor effectively turns it into a generator (since rotor speed is greater than synchronous speed), and I would like to capture the energy in a DC capacitor for measure. Right now, I'm thinking of using this open source project-https://github.com/Terbytes/Arduino-Atmel-sPWM as a variable frequency inverter drive with a H bridge to convert 12V DC to 220V AC for the motor. Any suggestion to how to effectively recapture the stored energy is much appreciated!
P.S. the motor is a fairly small single phase induction motor that draws in about 10W so probably no power semiconductors are needed.
