Volume Minimization of Current Type ACC with Rogowski Coil

This paper proposes a current type active common-mode noise canceller (ACC) using a Rogowski coil for common-mode (CM) noise detection. The proposed method reduces the volume of a noise filter more than that of conventional methods. The Rogowski coil is designed based on CISPR standards for detecting the target noise reduction and the frequency band. The proposed ACC with the Rogowski coil is evaluated in the experiment. As a result, the conducted emission voltage is reduced by 39dBμV.
