在以前的工作中，作者提出了一种有源共模滤波器（ACF），它能够降低连接到电源转换器的电源电缆的辐射噪声，并通过使用振荡器作为共模（CM）噪声源来评估其辐射噪声降低效果。在本文中，该ACF被应用到由PWM逆变器供电的电机驱动系统中，并评估了CM电压的衰减特性。为了避免ACF饱和，讨论了有源共模噪声抵消器与ACF的结合。实验结果表明，本文所构建的系统可以抑制由PWM逆变器产生的共模电压在一个宽的频率范围内，从100 kHz到100 MHz。
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.
