摘要
功率和效率是无线电能传输(WPT)电路的重要指标,而互感、负载等参数直接影响WPT的功率和效率特性。推导了电动汽车无线充电串/串并(S/SP)补偿拓扑电路的功率和效率表达式,并优化电路互感参数,使电路传输功率和效率达到整体最优设计。仿真和实验验证了S/SP补偿拓扑电路功效特性分析的可行性。
Power and efficiency are important parameters of the wireless power transfer（WPT） circuit,and the parameters of mutual inductance and load directly affect the output power efficiency characteristics of WPT.The expression for the power efficiency in electric vehicle wireless charging serial/serial parallel（S/SP） compensation topology is derived.The mutual inductance circuit parameters are optimized and the circuit to achieve the global optimal design is made.Simulation and experiments verify the feasibility of the S/SP compensation circuit topology efficiency analysis.
