ABSTRACT:
In one aspect, a polyphase power converter includes an input adapted to couple to a polyphase AC source, a positive DC output, and a negative DC output. The polyphase power converter also includes a first plurality of circuits and a second plurality of circuits. In one embodiment, each of the first plurality of circuits is adapted to receive a plurality of phases of the polyphase AC source and to produce a DC voltage at the positive DC output. Each of the second plurality of circuits is adapted to receive a plurality of phases of the AC source and to produce a DC voltage at the negative DC output. In one embodiment, the polyphase power converter includes a plurality of switching devices and each of the plurality of switching devices is adapted to isolate at least one phase of the polyphase AC source from at least one of the plurality of circuits.
