[其它]Common-mode current inductively coupled emission of AC PWM drives

Abstract—The most common solution for modern adjustable 1j0-9Kg'  
speed drives is the use of induction motors fed by voltage-source K^zDNIQU  
inverters. The inverters using fast switching insulated gate !Vheq3"q/  
bipolar transistors (IGBTs) generate pulse-width modulated k6!4Zz_8  
(PWM) voltage pulses. The high carrier frequency along with &-%X:~|:X  
fast rise and fall time of the PWM switching results in nontrivial ,m^;&&  
common-mode or ground currents noise. The current component MxOD8TDF4  
can cause electromagnetic interference (EMI) noise to neighbour +R6a}d/K  
equipments and installations by either radiation from the motor ubYG  
cable or by cross-talk (inductive and capacitive coupling) with Q6IQV0{p  
other conductors. This paper discusses the inductively coupled eWvo,
