A High Efficiency Nonisolated Buck–Boost Converter Based on ZETA Converter

摘要

In this paper, a new transformerless buckboost converter based on a ZETA converter is introduced. The proposed converter has the ZETA converter advantages, such as buckboost capability, input-to-output dc insulation, and continuous output current. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low voltage stress of the switch; therefore, the low
