Abstract:
A multiphase interleaved forward power converter includes an inductor and first and second subconverter comprising respective transformers. The converter also includes first and second drives configured to respectively operate the first and second subconverters with cycling periods comprising a conduction period, a reset period, and an idle period. The first and second drives are also configured to phase shift the cycling periods in each subconverter such that the conduction period of the subconverter is at least partially complementary to the idle period of the other subconverter. The second drive also clamps a voltage across a winding of the transformer of the first subconverter to substantially prevent a first resonance voltage from propagating in the first subconverter during the idle period of the first subconverter.
