摘要
提出了一种新型的电动汽车无接触感应充电系统及其电路拓扑结构,建立了基于互感理论的一次侧与二次侧的等效电路模型。分别为单负载和多负载系统推导出一次电路及二次电路的参数计算公式,得出了系统向负载传输的功率与电路参数之间的关系。设计了充电功率控制电路,提出了恒压、恒流等智能充电控制方法。采用pspice电路模型对系统进行了仿真,仿真结果验证了理论分析的正确性。
A novel contactless inductive charging system with its proposed, and the equivalent models for the primary and secondary circuits induction. The parameter calculation formulae of the primary and secondary circuit topology for electric vehicles is are built based on the theory of mutual circuits are derived respectively for both single load and multi-load system, and the relationships between the power transmitted from system to load and circuit parameters are obtained. The charging power control circuit is designed and the intelligent charging control schemes with constant voltage and constant current are put forward. Pspice circuit model is adopted to conduct simulation on the system. The results of simulation verify the validity of theoretical analysis.
