Elimination of Disturbing Components in the Harmonic Current and Torque Spectrum of Drive Systems by Making Use of Nonlinear Saturation Effects Inside the Motor and Improved Pulse-Width Modulation of the Power Converter

The efficient and safe control of electric power forms part of the key technologies of modern automated production. The proposed complete system approach implicitly takes into account a very detailed converter circuit representation with discrete electronic devices and an extensive 3D squirrel cage induction motor modeling by finite elements. The performed time domain analysis allows for a novel and deeper insight into the complete behavior of the electromechanical drive system.
