An LCL Composite Resonant-Type Bi-directional Contactless Power Transfer Mode

摘要

摘要: 针对单级谐振的双向电能传输方式所存在的谐振容量小及器件应力大等缺点,提出一种基于LCL复合谐振的对称拓扑双向电能传输模式.建立了系统的交流阻抗模型,推导了系统输入输出增益,并分析了不同负载下系统的频率响应及不同负载与耦合系数下输出功率特性.在此基础上,给出一种基于能量注入和自由振荡双工作模式切换的输出电压调节方法,并给出一种切换占空比控制方法以保证输出电压的恒定.仿真与实验数据表明:基于双工作模式的双向电能传输模式能有效地实现能量双向传输,输出的电压纹波始终小于0.3 V,同时该模式还具有相对简单、易于实现的特点.

Abstract: Classical single-load bi-directional inductive power transfer systems have some drawbacks such as low resonant capacity and high voltage and current stress of switching devices. Based on LCL composite resonance, a bi-directional power energy transfer mode using symmetric topology was proposed. The impedance model for alternating current was presented and the gain between the input and output was deduced. By analyzing the frequency responses and the output power under different loads and coupling coefficients, an output voltage regulation method was proposed, which runs in the bi-operation mode between energy injection and free running. Furthermore, a duty cycle control method for the bi-operation mode was also proposed to guarantee the stability of output voltage. The simulation and experimental results indicate that the proposed mode can achieve bi-directional energy transmission and the output voltage ripple less than 0.3 V. Moreover, this mode is simple and easy for implementation.
