基于CLC型无线电能传输系统研究

Research on Wireless Power Transmission System Based on the Type of CLC

针对多负载长距离供能问题,提出了一种多负载长距离无线能量传输系统,该系统使用中继线圈来增加电能传输的距离,与现有的大多数含中继线圈、负载仅与最后一个线圈连接、中继线圈仅充当功率继电器的无线能量传输系统不同的是,在所提出的系统中,中继器同时为多个负载供能。中继线圈不仅向下一级的线圈传输能量,也为与该线圈相连的负载传输能量。中继线圈采用CLC型补偿网络结构,具有恒流输出特性,能够实现负载独立的特性,可以在不影响其他负载的同时,灵活地调节某个负载的功率。对该系统建立了数学模型,分析了该系统的工作原理、负载电流特性和系统效率,最后搭建了一个六级负载的实验平台,验证了该系统的有效性和可行性。

According to the problem of supplying power for long distance multi-load,a kind of the system of long distance multi-load is proposed with wireless power transmission which use repeating coils to increase the distance of power transmission.Being different from most of the repeating coil in wireless power transmission system.where the load is only connected to the last coil and the repeater coil function as power relays,in the proposed system,the repeaters power for multiple loads.The repeater coils transmit energy not only to the subsequent coils,but also to the loads connected to them.The repeater coil adopts the type of CLC compensation network structure with constant current output characteristic which can realize the characteristic of load independence and flexibly adjust the load power without affecting each other.A mathematical model is established for the system and the working principle,load current characteristics and system efficiency of the system are analyzed in detail.Finally,an experimental platform with six levels of load is built to verify the effectiveness and feasibility of the system.
