一种新型反向耦合电感高变比双向DC-DC变换器

A novel high-conversion-ratio bidirectional dc-dc converter with coupled inductor is proposed in this paper. Compared with the bidirectional converters based on coupled inductor, this new topology can realize a higher step-up voltage gain and lower step-down voltage gain with a lower turn ratio in an appropriate duty cycle. In proposed converter, the windings of the coupled inductor are reversely ...
