Electromagnetic Compatibility (EMC) debugging of power electronics systems depends heavily on the experience of specialists due to the complex mechanisms of electromagnetic noise. In this paper, the time domain approach is used instead of the conventional frequency domain method to identify noise propagation path. The proposed test mode switches the upper or lower transistors of the converter legs...
Filters used in EMI suppression are often described in literature on drive system and have become a standard solution in industry. The effect of the commercial off-the-shelf filter depends significantly on how it is installed. A model that includes the installation parameters is made first and then the parameters of the model are extracted by transfer ratio measurements. One possibility is to include...
Electromagnetic compatibility is becoming an essential consideration for variable speed drive systems. Many methods are proposed to predict the conducted electromagnetic interference level. They ask to model all components of the drive system including cable and motor. In this paper, it is supposed that the measured noise level is determined in two phases. The first is the main noise source level...
