Abstract
A multiphase interleaved forward power converter includes two or more subconverters and two or more subconverters clamping circuits. Each subconverter includes an input, an output, and a transformer coupled between the input and the output. The subconverters are phase shifted relative to each other such that a conduction period of one subconverter is at least partially complementary to an idle period of another subconverter. The clamping circuits each include a switching device coupled to at least one winding of the transformer of each subconverter. The clamping circuits each are configured to clamp a voltage across the at least one winding to substantially prevent a resonance voltage from propagating in the subconverters during their idle period. Additional example subconverters, clamping circuits, and methods for substantially preventing a resonance voltage from propagating in multiphase interleaved forward power converters are also disclosed.
