This paper shows how induction motor drive, can be simulated with modern simulation programs. The focus will be on OrCAD, which is one of the most widely used general-purpose simulation programs. Static power converters can be analyzed by means of widely available circuit simulation software packages such as PSpice. However, they are usually modeled as a set of real switches, which results in long execution times and possible convergence problems in the case of complex circuits. This paper presents a model to simulate a sinusoidal pulse width modulation (SPWM) for three-phase inverter fed induction machine using PSPICE. The proposed model are based on converter switching function rather then actual circuit configuration, and they are suited for steady state and large signal transient analysis at system level. The operation mode and simulation results are presented.
