Experimental Analyses of EMI Noise Separator for CISPR25

Abstract

In energy transmission systems, devices must be able to work safely with each other. Therefore, electromagnetic emission and susceptibility of the converting systems are expected to be in a certain range. electromagnetic propagation, especially by radiation and conduction, cannot be neglected in power electronics such as electric vehicle, microgrid, aerospace technologies. In order to examine and reduce the noise emitted by the devices, the noise should be separated into common mode and difference mode components. In this study, Shou Wang modeling, which is used to separate the noise components into related components, has been examined in order to analyze the noise components within the framework of the CISPR25 standard used for electric vehicles and redesigned. Circuit simulation and design were done and the results were compared. Thanks to these results, it has been seen that the circuit works efficiently up to 90MHz and gives 8dB S11 reflection parameter at the 108MHz threshold level. In addition, the separator circuit was used in a bidirectional DC-DC converter with a known EMI level of 1KW and the noise components obtained were compared with the components of the converter. As a result, it has been seen that the results obtained using the noise separator circuit are almost the same as the real results. In the 18 - 42 MHz range, only the results obtained with the noise separator are up to 8dBuV higher than the real results, other than that the results are exactly the same
