| Summary: | 碩士 === 國立成功大學 === 電機工程學系 === 104 === In this thesis, TSMC 0.18-μm 1P6M process is applied to implement the design of the thermoelectric energy harvesting interface circuit. A negative voltage transfer technique is proposed to improve the conversion efficiency of harvesting and suppling power to a load circuit. The loss of traditional two-stage harvesting and regulating circuit can be improved by adopting a three-switch negative voltage transfer structure. The overall thermoelectric energy harvesting interface circuit consists of a negative voltage transfer circuit, a transfer management circuit, a maximum power point tracking (MPPT) circuit, and a zero current sensing (ZCS) circuit. The overall chip die size is 1.040 mm* 1.042 mm. The peak conversion efficiency reaches 75%.
