Title: A High Efficiency Nonisolated Buck–Boost Converter Based on ZETA Converter
Abstract: In this paper, a new transformerless buck-boost converter based on a ZETA converter is introduced. The proposed converter has the ZETA converter advantages, such as buck-boost 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 on-state resistance of the main switch can be selected to decrease the losses of the switch. The presented converter topology is simple; hence, the control of the converter is simple. The converter has the continuous output current. The mathematical analyses of the presented converter are given. The experimental results confirm the correctness of the analysis.
