EMI Noise Separation Method for Three-Phase WBG Inverters With Low Sensitivity to Parasitic Parameters
Yu Zhang,Yanjun Shi,Hui Li +2 more
TL;DR: In this paper, a 20 dB attenuator is integrated to improve the flatness of the noise separator in the 150 kHz-30 MHz frequency range, which is 0.3 dB for common mode transmission ratio and 0.6 dB for differential modes transmission ratio.
