Abstract
Systems and methods of operating a voltage converter are provided. The converter includes an output inductor and an output capacitor coupled to a rectifier circuit. The converter also includes a clamp circuit having a clamping diode and a clamping capacitor coupled in series, with the serial combination in parallel with the output inductor. The clamp circuit can also include a recovery inductor coupled to the output capacitor, and a switch configured to selectively couple and decouple the recovery inductor in parallel with the clamping capacitor.
