N2 - This paper proposes a novel type of an active common noise canceler (ACC) combining feedforward and feedback control. The ACC attenuates the common-mode (CM) voltage and suppresses EMI emissions by adding the CM voltage of reverse polarity to the CM voltage generated by inverters in AC motor drive system. The proposed ACC uses feedforward and feedback control whereas the original ACC [19] uses feedforward control only. Experimental evaluation is presented for comparison between the proposed ACC, a feedforward ACC, and commonmode chokes (CMCs) which are widely used as passive filters. The experimental results show that the proposed ACC has large CM voltage attenuation of up to 50 dB in the wide frequency range. The attenuation performance of the proposed ACC is larger than the feedforward ACC and a CMC, which uses the same ferrite core and windings used in the proposed ACC.
