Abstract
An energy recovery snubber circuit for a bidirectional power converter, a method of operation thereof and a power plant employing the bidirectional power converter. The bidirectional power converter has first and second inputs, an inductor coupled to the first input and a power switch coupled between the inductor and the second input. In one embodiment, the energy recovery snubber circuit includes: (1) a clamping capacitor coupled to the second input; (2) a clamping diode coupled between the clamping capacitor and the first input; and (3) a snubber inductor coupled to a node between the clamping capacitor and the clamping diode.
