摘　　要：基于磁耦合谐振技术搭建了一套完整的电动汽车无线充电系统。初级侧电路中采用交错并联PFC解决谐波污染问题,第一级BUCK电路进行恒功率控制,将直流电输送给全桥逆变电路进行DC/AC变换,得到交流方波电压送至磁耦合谐振机构,次级侧电路进行同步整流滤波,经过第二级BUCK电路后对电池进行三段式充电。通过Simulink对PFC、第一级BUCK以及逆变电路进行仿真并分析验证仿真结果。Based on the magnetic coupling resonance technology,a complete set of wireless charging system for electric vehicles is built.Interleaved PFC is used in the primary circuit to solve the problem of harmonic pollution.The first BUCK circuit is used for constant power control.The DC power is transmitted to the full bridge inverter circuit for DC/AC conversion.The AC square wave voltage is obtained and sent to the magnetic coupling resonance mechanism.The secondary side circuit carries out synchronous rectification and filtering,and after the second level BUCK circuit,the battery is charged in three sections.The PFC,first BUCK and inverter circuits are simulated by Simulink simulation software,and the simulation results are analyzed and verified.
