This study mainly develops a high-efficiency single-input triple-outputs dc/dc converter (HSTDC) with a soft-switching technique for high step-up applications. In general, multiple output voltages with only one single input power source is always required for the applications of renewable energy or electric vehicles. At the high step-up operation, the proposed HSTDC has a high voltage conversion ratio to sustain the high-voltage dc bus for the utilization of dc/ac inverter. The proposed HSTDC uses a coupled inductor with lower turn ratios to achieve the high step-up voltage gain and adopts an auxiliary inductor to adjust the voltage of the auxiliary output terminal indirectly. Moreover, the utilization of voltage clamping and zero-current switching (ZCS) in the proposed HSTDC is helpful for accomplishing the goal of high-efficiency power conversion and three output voltage levels. In addition, the effectiveness of the proposed HSTDC is verified by rich experimental results.
