The technique of vector space decomposition control of three phase induction machine is presented in this paper. By vector space decomposition the analytical modeling and control of machine are accomplished. The space vector decomposition technique limits the 5th, 7th, 17th, 19th….harmonic currents, which in such a system is otherwise difficult to control. This synopsis present harmonic analysis of motor current of medium and high power Variable Frequency Drive (VFD) Systems. Computer simulation of an IGBT fed induction motor based on constant voltage/frequency (V/f) operation is implemented using simulation software.
