Abstract

Based on the abc fundamental reference axis system, the dynamic process of an AC machine with PWM control is discussed in detail. The induction machine is a nonlinear high-order system. This system becomes more complicated when a nonsinusoidal PWM power source is introduced to the motor. Therefore, the machine behaves in a continuous periodic transient process. States according to switch pattern for the machine performance supplied by PWM including dead-band interval preventing shoot-through fault are studied in detail; a mathematical model is established. The performance of machine powered by PWM is explored based on abc frame. The simulation result using MATLAB is also presented
