Abstract :
This paper describes the phenomena of propagation of common mode high-frequency currents (HF) in the metallic parts of AC machines supplied by pulse width modulation (PWM) inverters. A detailed analysis based on finite elements modeling is proposed to identify the privileged paths of these HF currents and parameters that rule this phenomenon.
