A zero-voltage-switching (ZVS) buck-boost converter with a coupled inductor based on magnetic materials is proposed in this paper. An auxiliary circuit consisting of an additional winding to the main inductor, an auxiluary inductor, and an auxiliary diode is utilized to obtain the ZVS operation of power switches. Due to the ZVS operation, the switching loss is significantly reduced. The operation principle and steady-state analysis of the proposed converter are provided. A prototype of the proposed converter is developed, and its experimental results are presented for validation
