摘要：There is serious conducted electromagnetic interference ( EMI) in the application of medium-power variable-frequency drive ( VFD) systems. The EMI passive filters which can suppress the noise can make the VFD systems comply with the relevant electromagnetic compatibility ( EMC) standards. In this paper, combined with the experiment and measuring experience in related subjects, it describes the proper use of the filter, and does the EMI noise test. At the same time, a series of corrective measures and precautions are summed up. The final results testified the filter and the corrective measures have a good effect on EMI noise suppression.
