用于双级电极旋转驻极体能量采集器的自供电同步电荷提取整流器

This article presents for the first time the development of a self-powered synchronous electric charge extraction (SECE) circuit for an in-plane rotational electret kinetic energy harvester (EH) with a cold start function. As an electret EH features low source current and high output impedance, its output power is sensitive to the leakage current and the parasitic capacitance. A novel dual-stage e...
