| Abstract |
This paper examines the performance of EMIinput filters for SiC-MOSFET-based automotive DC-ACinverters on the DC side. The filter performance is eval-uated based on its ability to attenuate electromagneticinterference (EMI) according to the system requirements.The attenuation of EMI filters is greatly affected by themutual couplings between filter components and theirparasitic elements. As a result, a comprehensive set ofdesign principles is formulated to optimize the perfor-mance of EMI filters, taking into account these crucialfactors. Moreover, various configurations of EMI inputfilters, including 1-stage and 2-stage filters, are investigatedto determine their attenuation levels. Additionally, EMImeasurements are conducted using these filters to observetheir performance with respect to parasitic elements andmutual couplings. |
