Abstract: In this paper, a step-up converter is presented, which possesses a high voltage gain, a continuous input current, and galvanic isolation. This converter is applied to a thermoelectric conversion system along with the maximum power point tracking (MPPT) based on three-point-weighting method, so as to extract energy from heat via the thermoelectric module effectively. For LED dimming to be considered, a switched LED module is used to adjust the number of LEDs in LED strings, so as to achieve a dimmable function. Moreover, a field-programmable gate array (FPGA) chip, named EP1C3T100C8N made by Altera Co., is used as a control kernel, so as to realize not only MPPT but also LED dimming. Eventually, several thermoelectric modules, manufactured by Kryotherm Co., are used to verify the effectiveness of the proposed thermoelectric conversion system.
