Beschreibung
Zusammenfassung:	The invention provides a non-isolated soft switch high-gain DC/DC converter comprising two power inductors, one auxiliary inductor, two power switches, one bidirectional controllable auxiliary switch and n voltage multiplying units. Each voltage multiplying unit is a unit which is composed of two diodes and two capacitors and is provided with four ports. Compared with existing non-isolated high-gain boost topology, adjustable high gain can be realized, zero-voltage turning-on and zero-voltage turning-off of all switching tubes can be realized, and zero-current turning-off of all the diodes can be realized. Besides, voltage stress of switching devices is greatly reduced, and overall working efficiency of the converter is enhanced.
