摘要

远程无线开关控制面板的应用大大改善了人们的生活质量。研究了一种电磁式冲击能量收集器，实现了无线开关面板的无电池、自供能工作。提出了E型和U型两种铁芯的冲击式能量收集器结构，分析了工作原理。采用ANSYS Maxwell软件分析了收集器的磁力线分布、输出电压、输出功率等性能，完成了样机尺寸的优化设计。加工组装了E型铁芯的样机，完成了测试。结果表明，样机输出电压为12 V，转换的电能为0.66 mJ。以该收集器供电，无线开关面板发送了时长18 ms,1.1 kHz的方波，在接收端实现了LED的开关控制。

Abstract

An electromagnetic shock energy harvester was studied systematically for realizing the self-powered operation of a remote wireless switch.Two kinds of harvesters were proposed, which were installed with E and U-shaped iron core, respectively.The working mechanism was discussed.The ANSYS Maxwell was used to analyze the flux distribution, output voltage and power of the two harvesters.The harvesters’ optimized sizes were studied and a prototype with an E-shaped iron core was fabricated and measured.The results show that the harvester can generate 12 V electric voltage and 0.66 mJ electric power.A wireless switch, powered using the harvester, has transmitted 18 ms, 1.1 kHz square wave, and lighted up a LED on the wireless receiver.
