摘　　要：研究了低压输入、适用于电动自行车的无线充电系统。基于串联-串联耦合谐振的方法,依次设计了系统发射侧逆变器及其谐振网络、接收侧整流器及其谐振网络及用于充电与调节功率潮流的负载匹配变换器,重点对负载匹配变换器进行了小信号建模并设计了功率调节的控制策略。样机以d8PIC控制器为核心,实现了不同工况下的无线功率传输,并针对气隙距离、输入输出功率和效率等重要指标的静态映射关系进行了实验分析。A low vohage input wireless charging system electric bicycles is proposed.Based on the series-series reso- nant structure, the main power stages of the system is evaluated and designed, including the sending-side inverter with its resonant network,the receiving-side rectifier with its resonant network,and the load matching converter.Small sig- nal modeling and linear control technology is applied to the load matching converter for input voltage control which could effectively control the wireless power flow.Prototype is built with a dsPIC digital signal controller and the tests are performed on several critical aspects which quantify the static representation relationship of the proposed charging system including air-gap length, power flow regulation and the efficiency.
