Abstract :
The paper deals with the numerical modeling of a pulse-width modulated voltage IGBT or IGCT inverter-fed induction motor drive for the common and differential current modes. The proposed model of the drive respects the influence of the feeding cable described by the lumped or distributed parameters. The theoretical analysis is supplemented by results of relevant simulations and experiments. Evaluated are also the frequency characteristics of selected parts of the system and their contributions to its resultant harmonic spectra.
