摘要
针对电动汽车的充电问题,文中设计一种基于磁场共振式充电的电动汽车无线充电系统。该系统使用磁场中共鸣的原理将充电线圈输入端的交流电无线发送给输出端供电动汽车充电,同时输入端使用控制电路和高频逆变电路将直流电转化为交流电,输出端使用采集电路实时测量电池电压与电流反馈给输入端。基于Altium Designer 10软件的仿真与测试结果表明,所设计的系统在充电过程中电压波形较为平滑,控制系统具有较好的开关特性,且能实现较高的充电效率。
A wireless charging system based on magnetic field resonance charging is designed for electric vehicles to solve the charging problem of electric vehicles. In the system,the alternating current at the input end of the charging coil is wirelessly transmitted to the output terminal for charging of electric vehicles in accordance with the magnetic field resonance principle. At the input terminal,the direct current is converted into alternating current by means of the control circuit and high-frequency inverter circuit. At the output terminal,the voltage and current of the battery are measured in real time and fed back to the input terminal by means of the acquisition circuit. The results of simulation and test based on the Altium Designer 10 software show that the designed system has smooth voltage waveforms during the charging process,and its control system has good switching characteristics,which can achieve a high charging efficiency.
