摘要针对无接触供电(CPT)系统负载切换时造成原边回路的导轨电流变化和副边电路输出电压不恒定的问题, 提出一种双LCL补偿结构, 利用LCL特性实现原边电缆的电流恒定控制以及副边输出电压恒定控制。文中给出了双LCL补偿的CPT系统电路模型, 分析了原边和副边电路工作条件和特性, 并通过推导给出了各元件参数的设计方法。仿真和实验结果表明, 采用双LCL补偿技术降低了CPT系统复杂性, 较好地满足了原副边控制要求。

Abstract：In a contactless power transfer system, a constant current on primary winding determines the stability and power transfer capability of the entire system, and a constant voltage on pickup is absolutely necessary in practical applications. In this article, double-LCL compensation is presented which accomplished both constant current and constant voltage. The circuit of contactless power transfer system based on double-LCL compensation is given. The paper has a detail discussion of primary side and secondary side operating principle and its requirements. At the same time, the parameter of each component is inferred. Finally, its feasibility is verified by means of simulation and prototype. The solution presented in this article reduces IPT complexity and increases application availability.

Key words： Conteetless powor transfer constant current constant voltage reflected impedance compensation circuit
