Abstract

This paper presents a high voltage gain dc-dc converter operating with soft switching, high switching frequency, and reduced voltage stress in all semiconductors, which is suitable for applications as renewable energy sources. The proposed topology uses the coupled inductor and voltage multiplier cell techniques to obtain high voltage gain. The switch turn-on and turn-off occur with zero voltage switching (ZVS). The soft-switching range is independent of the load and is maintained from nominal output power to light load operation with reduced conduction losses. The theoretical analysis and experimental results of a prototype with 94.55% efficiency at nominal output power (200 W) operating with voltage gain equal to 15 times are presented in this paper.
