In this paper, an isolated single-ended primary-inductive converter (ISEPIC) with a soft-switching cell for implementing features of zero-voltage switching (ZVS) and zero-current switching (ZCS) is proposed. The ISEPIC has the following advantages: (1) By changing the inductor element of the ISEPIC into a transformer element, the features of electrical isolation can be achieved. (2) By incorporating a soft-switching cell, the power switches (MOSFETs) of the ISEPIC can achieve ZVS and ZCS features during turn-on conditions. Therefore, the power losses of the power switches can be reduced during the turn-on transient, and the overall efficiency of the ISEPIC can be increased significantly. Finally, a prototype of the ISEPIC with a soft-switching cell is built. Experimental results are presented to verify the performance and feasibility of the proposed ISEPIC for implementing features of ZVS and ZCS.
