This paper presents a methodology for assessing the impact of critical components in a PWM VSI servo drive on conducted electro-magnetic interference. Conducted emissions at the ac mains input are caused in part by the coupling and leakage of high frequency common-mode currents through complex return paths in the drive system. Common-mode currents are caused by switching of IGBTs at high slew rates...
This paper presents a modeling approach to simulate conducted emissions in PWM inverter driven PMSM servo drives to help designers to get a deeper understanding of interaction of common-mode noise sources and various circuit elements in a servo drive system. Conducted emissions at the ac mains input are caused by coupling and leakage of high frequency common-mode currents through complex return paths...
