Abstract:This paper presents a single-inductor bipolar-input bipolar-output(SIBIBO) DC-DC converter for thermolectric energy harvesting. With an advanced topology, the converter can not only extract energy with bipolar input voltages but also generate bipolar output voltages. To improve the conversion efficiency, the open-circuit voltage maximum power point tracking method is applied in this design. In addition, a precise VCO is proposed to dynamically adjust the switching frequency according to the input voltage. Desi… Show more
