一种无反向恢复问题的全软开关超高升压二次型变换器

This article presents a new ultrahigh step-up converter with fully soft switching conditions. In the proposed converter, ultrahigh voltage gain (VG) is obtained by combining the coupled inductors (CIs), voltage multiplier cell, and the quadratic structure. To provide soft switching conditions, an active clamp circuit is used to recover the leakage inductances energy as well as boost the VG. As a r...
