摘　　要：电动汽车在连接电网进行补能时,可能会对外产生电磁辐射骚扰。相关标准规定,在进行电磁辐射骚扰测量时必须采用人工电源网络,然而这一要求与其他用电设备的测量要求以及人工电源网络的频率适用范围并不一致。文章构建车辆充电时的高频电路模型,从差模干扰和共模干扰两个方面深入分析引入人工电源网络所带来的影响。同时,设计比对验证试验,以证明在高频情况下人工电源网络对辐射发射测量的影响较小,且在某些测试场景中可以简化试验布置,进而提高试验效率。When electric vehicles are connected to the power grid for replenishment,electromagnetic radiation disturbance may occur.The relevant standards stipulate that the artificial mains network must be used in the measurement of electromagnetic radiation disturbance,but this requirement is not consistent with the measurement requirements of other electrical equipment and the frequency application range of the artificial mains network.In this paper,the high-frequency circuit model of vehicle charging is constructed,and the impact of introducing artificial mains network is analyzed from two aspects:differential mode interference and common mode interference.At the same time,the comparison test is designed to prove that the artificial power supply network has less influence on the radiation emission measurement under high frequency conditions,and the test arrangement can be simplified in some test scenarios,so as to improve the test efficiency.
