摘要
相对于传统的电感电容( LC)谐振型感应电能传输系统,串并联(LCL)谐振型感应电能传输系统有更大的功率传输能力,但其特性更为复杂。针对 LCL型感应电能传输系统的高阶非线性和复杂的频率特性,利用系统的互感耦合模型,对系统的谐振参数匹配方法、变负载情况下系统的频率特性以及功率传输特性进行了分析研究,给出了系统原边谐振参数、传输功率和效率的计算方法,最后通过仿真验证了理论分析的正确性。
Abstract
The Inductor Capacitor Inductor(LCL) type Inductive Power Transfer(IPT) system is a kind of new resonant topology for IPT system,with a larger power transfer capability and a more complicated frequency characteristic than the conventional LC resonant one. To deal with the high order nonlinear and complex frequency characteristics, the resonant parameter compensation method is presented by impedance analysis based on the mutual coupling model. The frequency and power transfer performance with load variation are analyzed and then the power transfer and efficiency computing method are presented. Simulation results have verified the theoretical results.
