In recent years, piezoelectric materials have been widely investigated for harvesting energy from ambient vibrations. A vibrating piezoelectric device (PD) generates alternating current (AC), which needs to be converted into direct current (DC) for powering electronic devices or for storage. A traditional full-wave bridge rectifier (FBR) interface circuit serves this purpose, but it suffers from high power loss due to the presence of high forward voltage across the diodes. In this article, an improved H-Bridge rectifier circuit is proposed as the AC-DC rectifier circuit to reduce power loss for high frequency and low amplitude application. The performance of the proposed rectifier circuit was experimentally studied, analysed and discussed. Two different testing scenarios for high frequency, namely, varying input power with fixed excitation frequency and varying excitation frequency with fixed input voltage were considered. Applicability of the circuit at low frequency range was also investigated. The outcome shows that the proposed circuit notably increases the voltage and the power produced from the PD when compared to traditional FBR circuits.

一种用于压电能量收集系统电压整流的改进型自供电H桥电路
近年来,压电材料已被广泛研究用于从环境振动中收集能量。振动压电设备 (PD) 会产生交流电 (AC),需要将交流电转换为直流电 (DC),以便为电子设备供电或存储。传统的全波桥式整流器 (FBR) 接口电路可用于此目的,但由于二极管两端存在高正向电压,因此功率损耗高。在本文中,提出了一种改进的 H 桥整流电路作为 AC-DC 整流电路,以减少高频和低幅度应用的功率损耗。对所提出的整流电路的性能进行了实验研究、分析和讨论。两种不同的高频测试场景,即 考虑了在固定激励频率下改变输入功率和在固定输入电压下改变激励频率。还研究了电路在低频范围内的适用性。结果表明,与传统的 FBR 电路相比,所提出的电路显着增加了 PD 产生的电压和功率。
