Analysis and implementation of an interleaved high step‐up converter with reduced voltage stress an interleaved high step‐up DC‐DC converter with ZVS

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Abstract A new symmetrical structure of the interleaved converter type is proposed in this paper to obtain high voltage gain. The proposed converter delivers a very high voltage ratio using the coupled inductor technique and switched capacitor, and all this happens at a moderate duty cycle. Furthermore, the MOSFETs have low voltage stresses. Therefore,
