摘　　要：考虑到CISPR 32 ED3委员会草案(CD)文件中增加了针对无线功率传输(WPT)端口设备辐射发射测试要求,文章对草案CIS/I/655/CD和CIS/I/671/CD中WPT相关的测试方法和限值等进行了总结。基于草案中9 kHz~30 MHz限值,对电磁兼容(EMC)实验室辐射发射测试系统的测试能力进行了摸底,并对两款具有WPT充电功能的产品进行了9 kHz~30 MHz辐射发射测试,研究了产品在该频段辐射发射的符合性情况,旨在为后续CISPR 32涉及WPT的9 kHz~30 MHz辐射发射内容修订提供参考。Considering that the Committee Draft(CD)documents of CISPR 32 ED3 have added radiated emission test requirements for Wireless Power Transfer(WPT)port equipment,this paper summarizes the WPT-related test methods,limits,etc.in the two committee drafts of the CISPR 32 ED3,i.e.CIS/I/655/CD(202205)and CIS/I/671/CD(202401).The test capability of the radiated emission measurement system in the EMC laboratory based on the limit value of 9 kHz~30 MHz in the two versions of CD documents has been investigated,and the compliance of the radiated emission of the WPT products in this frequency band was studied by conducting 9 kHz~30 MHz radiated emission tests on two products with integrated WPT charging function.The aim is to provide a reference for subsequent revisions to the CISPR 32 standard concerning the section on WPT 9 kHz~30 MHz radiation emission.
