介绍了一种高功率密度宽带隙四极DC/DC升压变换器的电磁干扰抑制方法。作者介绍了一种新的方法来表征电磁干扰的WBG电力电子。该转换器的物理紧凑型设计及其外壳会引起共模EMI的问题，导致电磁兼容性（EMC）合规性测试失败。利用共模等效建模（CEM）和快速频域电路分析，这种方法允许设计人员评估共模EMI问题独立于混合模式的测量和设计相应的优化滤波器。
This article demonstrates the reduction of electro-magnetic interference (EMI) in an enclosed high-power-density wide-bandgap (WBG) four-pole DC to DC boost converter. The authors introduce a new methodology for characterizing the EMI in WBG power electronics. The converter’s physically compact design and its enclosure induce a problematic level of common-mode EMI that leads to failure of electromagnetic compatibility (EMC) compliance tests. Utilizing common-mode equivalent modeling (CEM) and rapid frequency-domain circuit analysis, this methodology allows the designer to assess the common-mode EMI problem independently from the mixedmode measurements and design an optimized filter accordingly.
