摘要

提出了一种基于双叠谐振的单电感双源能量收集电路，并结合最大功率点跟踪技术。它采用升压接口电路转换来自光伏(PV)电池和热电发电机(TEG)的能量。该电路包括三种工作模式:单热电模式(STM)、单光电模式(SPM)和双源模式(DM)。根据两个电源是否达到其最大功率点，自动选择三种模式。根据仿真结果。接口电路的峰值转换效率为86.3%，两个光源的最大功率转换效率分别为98.75%和99.1%。

Dual-Source Energy Harvester with MPPT Technology based on Double Stack Resonance

This paper proposed a single-inductor dual-source energy harvesting circuit with maximum power point tracking (MPPT) technology based on double stack resonance. It employs the buck-boost interface circuit to convert energy from a photovoltaic (PV) cell and a thermoelectric generator (TEG). The proposed circuit includes three operating modes called single thermoelectric mode (STM), single photoelectric mode (SPM) and dual-source mode (DM). The three modes are automatically selected according to whether the two sources reach their maximum power point. According to the simulation results. The peak conversion efficiency of the interface circuit is 86.3% and the MPPT efficiencies of the two sources are 98.75% and 99.1 % respectively.
