基于同步电荷提取和翻转的可扩展异质能量俘获电路
Extensible Synchronous Charge Extraction and Inversion for Heterogeneous Energy Harvesting Circuit
摘要
Abstract
In order to provide more stable and reliable energy,an extensible synchronous charge extraction and inversion for heterogeneous energy harvesting(EH-SCEI)circuit is proposed for the hybrid energy harvesting of heterogeneous energy.The proposed EH-SCEI circuit uses a passive peak detection circuit and an RC differential circuit to achieve simultaneous extraction of heterogeneous energy sources at piezoelectric voltage peaks,and part of the charge is extracted to the energy storage capacitor while the remainder is flipped to improve en-ergy harvesting efficiency.Both theoretical simulation and experimental test demonstrate that the proposed circuit can harvest energy from multiple piezoelectric transducers(PZTs)with arbitrary phase differences and can be extended to practical application scenarios.The per-formance in terms of input and output range,load correlation and harvesting efficiency is improved compared to existing circuits.关键词
