摘要：

In this paper, a soft-switching single-ended-primary-inductance converter (SEPIC) with multi-output sources is proposed. The proposed SEPIC has the following advantages: (1) The conversion efficiency can be increased. To incorporate a soft-switching cell with a flyback-type, the power switches can achieve zero-voltage-switching (ZVS) and zero-current-switching (ZCS) features under turn-on transitions, resulting in reducing the switching losses and electromagnetic interference (EMI); (2) The applicability can be maximized. To apply the voltage ratio of the transformers, the proposed SEPIC has multi-output sources with step-up/down voltage functions. Finally, a prototype of the soft-switching SEPIC with multi-output sources is built and implemented. Simulated and experimental results are presented to verify the performance and the feasibility of the proposed soft-switching SEPIC with multi-output sources.
