Abstract :
In this paper, characteristics of conducted electromagnetic interference (EMI) emissions of three phase voltage source PWM inverters are presented. The conducted EMI emission levels of PWM inverters on various patterns: SPWM, DPWM60° and THIPWM techniques are focused. The experimental results of common mode EMI noises from the inverters are analyzed at the different modulation index and at various frequencies conditions. The results show the phenomena of EMI noises from the PWM inverters affect to intra systems.
