Abstract :
A time-domain equivalent network model is presented, in the natural ABC frame of reference, for computer-aided prediction of the performance of DC source-inverter fed induction motor systems and verified experimentally. The choice of this frame of reference for stator representation facilitates the integration of the machine and the electronic DC source-inverter models into one global equivalent network for the entire system. This model is most suited for the propulsion and actuation class of drives in which induction motors may substitute for brushless DC motors as prime movers. The model was used to simulate the performance of a 204 V, 1/3 hp, 60 Hz, 8-pole induction motor-inverter system, and the results were verified by test results obtained in the laboratory. The model was applied to a 440 V, 15 hp, 60 Hz, 8-pole induction motor-inverter system for purposes of evaluating the effects of 180° e and 120° e inverter conduction periods on the currents and torque profiles of the drive system
