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。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.
