一种基于耦合电感的超高升压二次型Boost变换器

In this article, an ultrahigh step-up quadratic boost converter based on coupled-inductor is proposed. The voltage gain of the proposed converter can be enhanced significantly by increasing the duty cycle due to the quadratic boost structure. A coupled-inductor integrated with a voltage doubler cell is applied to further improve conversion ratio and reduce voltage stresses. The leakage inductor cu...
