电动汽车30 MHz以下磁场辐射骚扰标准解析与验证

Analysis and Verification of Magnetic Field Radiation Disturbance Standard for Electric Vehicle Below 30 MHz

深入剖析了CISPR 36:2020中电动汽车30 MHz以下磁场辐射骚扰的测试布置、测试工况、测试过程、限值等,详细阐述了CISPR 36:2020和GB/T 18387-2017磁场辐射骚扰测试的技术差别。以典型的纯电动汽车为例,分别根据CISPR 36:2020和GB/T 18387-2017磁场辐射骚扰测试要求进行了验证试验,试验结果与标准的限值比较表明,CISPR 36:2020规定的限值更为宽松。

In this paper,the test configurationt,test conditions,test procedure and limits of magnetic field radiation disturbance of electric vehicles below 30 MHz in CISPR 36:2020 are analyzed in depth,and the technical differences between CISPR 36:2020 and GB/T 18387-2017 are elaborated in detail.Taking a typical pure electric vehicle as an example,the verification tests are carried out according to the magnetic field radiated disturbance test requirements of CISPR 36:2020 and GB/T 18387-2017 respectively.The comparison between the test results and the limits value shows that the limit specified by CISPR 36:2020 is more relaxed.
