基于双LCL变补偿参数的磁耦合谐振式无线充电系统研究
|
摘要
为了简化磁耦合谐振式无线充电系统电路设计和控制的复杂性,提出一种双LCL变补偿参数的磁耦合谐振式无线充电系统,只需对部分补偿元件进行投切操作,即可实现恒流和恒压充电。首先利用二端口网络对系统原边、副边建模得到双LCL数学模型,分析实现恒流或恒压输出的参数配置条件;然后根据恒流和恒压参数配置特点,设计变补偿参数的电路结构;再根据仿真方法得出的关键参数与系统传输特性之间的关系,合理设计参数配置,使得磁耦合谐振式无线充电系统无复杂电路环节而且控制简单,还可实现原边电流和频率恒定;最后搭建实验平台,验证设计的系统输出的电压或电流波动较小,可以满足恒压和恒流充电的要求。
In order to simplify the circuit design and control complexity,a magnetically-coupled resonant wireless power transfer(MCR-WPT) charging system was proposed based on double-sided LCL compensation alteration.Through adjusting compensation network,constant voltage(CV) and constant current(CC) charging modes can be achieved.First,mathematical model was obtained by modeling primary and secondary sides of double-sided LCL using two-port network method.The parameter configuration condition for CV or CC output was analyzed.According to the characteristics of CV and CC parameter configuration,the circuit structure of compensation alteration was designed.In the light of the relationship between the key parameters and the system transmission characteristics,the reasonable parameter configuration was determined.The designed MCR-WPT charging system has the characteristics of no complicated circuit,simple control,constant primary current and constant frequency.Finally,an experimental platform was built.The experimental results show that the output voltage and current fluctuation of the system are small.The proposed scheme can meet the requirements of CV and CC wireless charging.
