In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the zeta converter advantages such as, buck-boost capability, input insulation and continuous output current. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one power switch is used. The proposed converter offers low voltage stress of the switch; therefore, the low on-state resistance of the power switch can be selected to decrease losses of the switch. The presented converter has the simple structure; hence, the control of the converter will be simple. The converter has the continuous output current. The mathematical analyses and principle of the proposed converter are explained. The validity of the proposed converter is confirmed by the simulation results via PSCAD software.
