A single-ended primary-inductance converter (SEPIC) is to be used at the output of a direct-methanol fuel cell (DMFC) system. In this paper, SEPIC is investigated in terms of the performance variations when the operating temperature changes from -50 degree Celsius to 71 degree Celsius. The efficiency of the converter is analyzed with respect to the temperature change. The temperature characteristics of passive elements such as resistors, capacitors and inductors are reviewed. A thermal model of a MOSFET is established, which leads into a thermal model of the converter circuit. The model is validated against results from experiments.
