摘要:
无线电能传输（WPT，wireless power transfer）技术目前已被应用到生产生活的很多领域，在WPT系统运行和调试时，需要对系统进行监测以了解系统的实际工作状况。给出了一种上位机与下位机结合的无线电能传输系统能效性能监测器设计方案，以LCC-S型磁耦合WPT系统为监测对象，对监测系统需求进行了分析，给出了WPT系统各能效性能参数的计算公式，提出基于STM32的下位机和基于PC与LabVIEW的上位机系统硬件和软件设计方法。最后通过实验验证了所提出的无线电能传输系统能效性能在线监测器设计方案和设计方法的合理性和可行性。
Abstract:
Wireless power transfer (WPT) technology has been applied to many fields of production and life. When the WPT system is running and debugging, the system needs to be monitored to understand the actual working conditions of the system. In this paper, a design scheme of energy efficiency monitor for wireless power transfer system combined with upper computer and lower computer was proposed. The LCC-S magnetic coupling WPT system was used as the monitoring object to analyze the monitoring system requirements. The calculation formulas of the WPT system energy efficiency parameters were given. The hardware and software design method of the lower computer based on STM32 and the upper computer system based on PC and LabVIEW was presented. The experiment results show the proposed design scheme and design method are suited for the energy efficiency online monitor of the wireless energy transmission system.
