摘要

为了利用能量收集实现无电池运行，一种基于降压开关电容的变换器被用作振动-电变换器。为了提高功率效率，本文设计了一种降压ACDC变换器，实现1/N (N=2,3，…)采用开关电容技术设计了转换模式。虽然传统的变换器通过调节储存在大电容器中的能量来提供输出，但所提出的变换器通过进行交流-直流转换来产生输出。因此，所提出的转换器可以提高功率效率。在功率效率方面，通过理论分析阐明了该变换器的有效性。通过仿真和实验验证了电路设计的有效性。

Design of a Step-Down AC-DC Converter for Energy Harvesting System Using Vibration-Based Energy

To realize battery-free operation employing energy harvesting, a step-down switched-capacitor-based converter has been used as a vibration-to-electricity converter. In this paper, to improve power efficiency, a step-down ACDC converter realizing 1/N (N=2,3,... ) conversion modes is designed by using switched-capacitor techniques. Although conventional converters offer an output by regulating the stored energy in a big capacitor, the proposed converter generates the output by performing AC-DC conversion. Thus, the proposed converter can improve power efficiency. Concerning the power efficiency, the effectiveness of the proposed converter is clarified by theoretical analysis. Furthermore, the validity of the circuit design is confirmed by simulations and experiments.
