High voltage gain single stage DC-DC converter based on three-state commutation cell

This paper presents a high voltage gain single stage DC-DC converter based on the three-state commutation cell. The presented converter operates with soft-switching ZVS mode for all switches. The operation principle, project specifications, and experimental results from a 500W prototype are presented in order to validate the proposed structure. The results show de soft switch commutation, reduced stress and high efficiency (over 94%).
