摘要

本文从时域和频域两个方面研究了DC/DC功率变换器系统在2 ~ 150khz频率范围内产生的传导辐射。对传导排放进行测量和评估，以参照现有标准评估系统的排放水平，并指出哪些测量设置可能对测量结果产生影响。实验采用了一种用于电动汽车的DC/DC电池充电器样机。结果表明，在2 ~ 150khz的频率范围内，DC/DC功率变换器系统可能不符合现有的一些标准，并且测量设置可能对传导辐射的评估产生重大影响

Measurement and Evaluation of the Conducted Emissions of a DC/DC Power Converter in the Frequency Range 2–150 kHz

In this paper the conducted emissions generated by a DC/DC power converter system in the 2–150 kHz frequency range are studied in both time and frequency domains. Measurement and evaluation of the conducted emissions are carried out to assess the level of the emissions of the system with reference to the existing standards and to point out which measurement settings may have an impact on the measurement results. A prototype of a DC/DC battery charger for electric vehicles was used in the experiments. The results show that the DC/DC power converter system may not result in being compliant to some of the existing standards in the frequency range 2–150 kHz and that measurement settings may affect significantly the evaluation of the conducted emissions_
