Abstract

Predicting and solving EMI emissions related to Common Mode (CM) ones in pulse with modulation PWM inverter induction motor drive systems requires various jequency-ependent efects to be considered. Thus, the application of active circuitry to increase the peformance per size and prevent dependency on some parameters of the motorfor Electro-Magnetic Interference (EMI) filter IS considered. The major problems are power line jequency rejection and the compensation of the feedback loop, which is influenced by the wide-ranging utility impedance. While analysis and simulations show. in the literature, that these problems prevent the practical application of active filtering to power supplies especially less than 100 kHz, the approximation with artificial neural networks demonstrate a good promise to take into Ihe parameters of the mo(or impedancefor independence of the filter easily. Thus, the proposed method allows another way to prevent the switching "oise applying to the conducted electromagnetic emissions generally caused by power supply firstly to switching conditions, then secondly to common mode condition of the motor drive system.
