摘　　要：研究了一种用于电动汽车无线充电系统的Z源逆变器控制方法。用Z源网络ZSN(Z-Source Network)代替了传统的逆变器前级boost电路称为Z源逆变器,可以仅对Z源逆变器进行控制就可以同时实现PFC和调节输出电压,同时提出了Z源不对称电压消除控制方法 Z-AVC(Z-source Asymmetrical Voltage-cancellation Control),使Z源逆变器工作在软开关状态,提高了系统效率。在MATLAB/Siumlink环境对带Z源逆变器的无线充电系统和Z-AVC控制方法进行了仿真,并搭建了硬件平台验证了该方案可行性。An advanced control method is introduced to electric vehicle wireless charging system with Z-source inverter.Using Z source network instead of the inverter front stage boost circuit and calling it Z-source inverter,it can inherently performs PFC and regulate the system output voltage simultaneously.A Z-source asymmetrical voltage-cancellation(Z-AVC)control is presented.It makes the inverter work in ZVS operation and improve the efficiency of the system.The simulation and experiment results validate that this Z-AVC could achieve the expected purposes.
