摘　　要：从电力电子系统常规电路的近场辐射模型出发,给出了近场探头的制作方法和校正曲线的提取办法;还给出了使用近场探头进行EMC故障诊断的方法和应用领域。实验数据为近场探头的应用提供了实践验证。Based on the radiation model of the normal circuits in power electronic system, the manufacture method of the near field probes and the way to obtain the performance factor curve of the probes are presented in this paper. Thereafter,the EMC trouble diagnosing techniques and their application areas are introduced.The validity of the techniques based on near field probes is verified by the experimental results.
