摘要
随着WPT应用的发展,多接收WPT系统因一个发射端可以为多个接收端同时供电,近年来受到广泛关注.对LCL-S型两接收端WPT系统的功率分配进行研究,并对LCL-S谐振补偿电路的两接收端WPT系统的传输特性进行分析,提出一种双PI功率控制,实现了发射电源恒功率控制.同时,通过移相控制调节各接收端的输出功率来实现按预设比例进行功率分配.仿真实验验证了所提出的方法实现恒功率输出和按预设比例分配接收端电能的可行性和有效性.
Abstract
With the development of wireless power transfer(WPT)applications,multi-receiver WPT systems has ac-quired wide attention owing to its ability of simultaneously providing power for multiple receivers by one transmitter.The present work studied the power distribution of LCL-S multi-receiver WPT system.It analyzed the transmission character-istics of two-receiver WPT system of LCL-S resonant compensation circuit,and proposed a dual-PI power control to real-ize constant control of transmitting source.Moreover,the phase shift control was used to adjust output power of each re-ceiver,thereby achieving power distribution according to the preset proportion.Simulative experiments verified the feasi-bility and effectiveness of the proposed method in providing constant power output and allocating power among various re-ceivers with the preset proportion.
