Abstract

This paper presents an energy harvesting interface for simultaneous extraction of bipolar thermoelectric generators (TEG) and photovoltaic cells (PV). The reconfigurable buck-boost converter topology is employed to convert positive or negative input voltages into positive output voltages. By periodically detecting the input conditions, the circuit automatically operates in single-source mode, dual-source integral multiplexing mode (DIMM), and double-stacking resonant mode (DSRM). In the DIMM, simultaneous extraction of positive TEG and PV energy is accomplished within one switching cycle. Compared to the single-source mode, the proposed DSRM increases the conversion efficiency by 5.5% with the same number of switch transitions for synchronous extraction of negative polarity TEG and PV. Utilizing adaptive impedance matching technology, the proposed adaptive maximum power point tracking controller achieves tracking efficiencies

采用堆叠谐振技术的可重构buck-boost转换器，用于双极性热电和光伏能量收集

提出了一种用于双极热电发电机（TEG）和光伏电池（PV）同时提取的能量收集接口。采用可重构的降压-升压转换器拓扑结构将正或负输入电压转换为正输出电压。通过周期性检测输入条件，电路自动工作在单源模式、双源积分复用模式（DIMM）和双堆叠谐振模式（DSRM）下。在DIMM中，同时提取正TEG和PV能量在一个开关周期内完成。与单源模式相比，该DSRM在同步提取负极性TEG和PV的情况下，转换效率提高了5.5%。利用自适应阻抗匹配技术，提出的自适应最大功率点跟踪控制器在超宽的源电阻范围内（10-1500 Ω）实现了90%的跟踪效率。转换器的实现是在0.18μm工艺中进行的。仿真结果表明，DIMM和DSRM的峰值转换效率分别为86.4%和88.1%。
