ABSTRACT:
The subject invention reveals a new coupled inductor boost converter which achieves zero voltage turn on switching for all four circuit switches. The coupled inductor of the circuit is fully clamped and thereby achieves excellent noise performance with neither snubbers nor clamps. The new coupled inductor boost converter is outstanding for isolated high voltage applications because the voltage stress of the secondary switches does not exceed the output voltage, it requires only one magnetic circuit element, and the average voltage stress of the secondary winding is equal to or less than half the output voltage.
