The aim of this paper is to study the effect of EMI in Switched mode PWM Inverter fed AC drive. This Switched mode PWM Inverter has an inherent noise source. This noise is mitigated by a New Active Common Mode Electro Magnetic Interference Filter (ACEF) which is proposed for switched mode power supply applications. The proposed filter is based on current sensing and a compensation circuit which...

This paper presents novel active filter for mitigation electromagnetic interference (EMI) and other adverse effects of pulse width modulation (PWM) inverter-fed AC motor system. An active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. This paper provides high frequency models ...
