摘要
针对无线电能传输系统中移相控制、级联DC/DC变换器等功率调节方法存在的不足,提出了一种基于短路解耦的WPT系统输出功率调节方法。首先,给出了双侧LCC补偿的WPT系统拓扑,推导了系统输出电流的表达式,分析了系统的工作特性。在此基础上,给出了短路解耦拓扑,分析了短路解耦的工作原理,并给出了双管控制下的输出功率调节方法。最后,通过仿真验证了该方法的可行性和有效性。
To overcome the shortcomings of power regulation methods such as phase-shifting control and cascaded DC/DC converter in wireless power transfer system,a power regulation method based on short-circuit decoupling for WPT system was proposed.Firstly,the double-sided LCC compensated WPT system is given,the expression of system output current is derived,and the working characteristics of the system are analyzed.On this basis,the short circuit decoupling topology is given,the working principle of short-circuit decoupling is analyzed,and the output power regulation method under the control of two transistors is also given.Finally,the feasibility and validity of the method are verified by simulation.
