The present paper deals with the development of a detailed identification method based on the frequency response of an induction machine in high frequency, the transfer function are used to represent a mathematical model of AC motor impedance. The proposed model of AC motor impedance is suitable for prediction and analysis the Electromagnetic Interference (EMI) problems in adjustable speed driver...
In Adjustable Speed Drives (ASD), high frequency parasitic currents cause several unexpected problems, such as premature deterioration of motor winding insulation and ball bearings. In order to understand and to mitigate electromagnetic disturbance it is necessary to use a precise model of the PWM inverter, the energy cable and the AC motor. In this paper, an equivalent circuit of the three phase...
The increase of switching speed and frequency in power electronics converters has greatly improved their performances and characteristics. These advantages are accompanied with the increased level of interference, so that EMI consideration is a major task for circuit designers nowadays. In Adjustable Speed Drives (ASD), the (dv/dt) leading to conducted emissions at high frequencies which are propagated...
