A Dual Load Wireless Power Transmission System Based on S-LCC Topology

在无线电能传输系统中,多负载的输出受到越来越多的关注,尤其是与负载无关的独立输出。在此处提出了一种基于S-LCC电路拓扑结构的双类型输出,可以同时实现负载端的一端恒压输出,另一端恒流输出。此拓扑结构与多线圈结构相比,节省了磁耦合线圈和补偿元器件,所提出的双类型输出可视为各自独立的输出端口,可独立调节,无需复杂的解耦条件,大大简化了参数的设计。此处详细分析了S-LCC拓扑结构的电路模型、工作原理,搭建了115 V的恒压输出和4 A的恒流输出样机,验证了所提拓扑结构的可行性。

In wireless power transmission system,the output of multiple loads is paid more and more attention,especially the independent output independent of load.A dual type output based on S-LCC circuit topology is proposed,which can realize constant voltage at one end and constant current output at the other end at the same time.Compared with the multi coil structure,topology saves magnetic coupling coils and compensation components.The proposed dual type output can be regarded as independent output ports,which can be adjusted independently without complicated decoupling conditions,which greatly simplifies the design of parameters.The circuit model and working principle of S-LCC topology are analyzed in detail.The 115 V constant voltage output and 4 A constant current output prototype is built,which verifies the feasibility of the pro-posed topology.
