Active clamp zero voltage soft switch high gain booster staggered parallel converter

This invention discloses active clamp zero-voltage soft switch high gain boost staggered parallel converters including two power switch tubes, two clamp switch tubes, two clamp capacitors, two continuing flow diodes and two coupled inductors, in which, each of the two coupled inductors includes three windings, which utilizes the second and third windings of the two coupled inductors to realize high gain output of the converter, utilizes a serial circuit composed of the two clamp switch tubes and two clamp capacitors to absorb and transfer harmlessly the leak energy of the two coupled inductors and realizes turn on of zero voltage of two power switch tubes and zero voltage turn-off of them utilizing the parallel capacitors of the two switch tubes to further realize zero-voltage turn on and off of the two clamp switch tubes.
