This paper studies the characteristics of SiC inverter powertrains on common-mode (CM) EMI emission. First, a CM noise source model of an EV powertrain is built. Then, the factors of switching frequency, switching speed, and switching ringing on the CM noise source are analyzed. Finally, experiments on a conducted EMI test-bed are carried out to verify the influence of SiC inverters on conducted CM EMI emission in EV powertrains.

SiC逆变器动力总成对共模EMI噪声的特性

本文研究了SiC逆变器动力总成在共模（CM）EMI辐射下的特性。首先，建立电动汽车动力总成的CM噪声源模型。然后，分析了CM噪声源上的开关频率，开关速度和开关振铃的因素。最后，在传导EMI试验台上进行了实验，以验证SiC逆变器对EV动力总成中传导CM EMI辐射的影响。
