Abstract

This paper presents a single-inductor triple-input dual-output buck–boost converter for the dual-source energy harvesting application. The converter employs the proposed series pile-up synchronized harvesting technique to improve the conversion efficiency at low input voltage and the system’s output power range. In parallel, to improve the tracking accuracy, a maximum power point tracking (MPPT) technique with coarse and fine tuning is incorporated into the harvester. In addition, to enable continuous energy extraction from transducers, a clockless-sampling technique is proposed. Implemented in the TSMC 0.18-

μ

m standard CMOS process, the converter achieves a peak conversion efficiency of 88.1% and a maximum output power of 10 mW at

采用无时钟采样和堆积技术的10mw输出功率范围和88.1%效率可重构DC-DC变换器，用于双源能量收集

本文提出了一种用于双源能量采集的单电感三输入双输出降压升压变换器。该变换器采用所提出的串联堆积同步采集技术，提高了低输入电压下的转换效率和系统的输出功率范围。同时，为了提高跟踪精度，收割机采用了粗微调的最大功率点跟踪（MPPT）技术。此外，为了实现从换能器中连续提取能量，提出了一种无时钟采样技术。该转换器采用台积电0.18 μm标准CMOS工艺实现，在VOUT=1.2V时，峰值转换效率为88.1%，最大输出功率为10 mW。
