Abstract

In previous work, the authors proposed an active common-mode filter (ACF) that is able to reduce the radiated noise from power cables connected to power converters and evaluated its radiated noise reduction effect by using an oscillator as a common-mode (CM) noise source. In this paper, this ACF is applied to a motor drive system fed by a PWM inverter, and the attenuation characteristics of the CM voltage are evaluated. In order to avoid saturation of the ACF, the combination of an active common-noise canceller and the ACF is discussed. The experimental results show that the system constructed in this paper can suppress the CM voltage produced by a PWM inverter over a wide frequency range, from 100 kHz to 100 MHz.
