Space-vector Modulation in a two-phase induction motor drive for constant-power operation

In the paper, a space-vector pulsewidth-modulation (SVPWM) inverter is proposed for constant-power operation of a two-phase induction motor. The operating principle of SVPWM is described, and the algorithm for constant-power operation is presented. Analysis for dynamic operation using a simple scalar control scheme is carried out and parameters for implementation of the scheme are obtained. Experimental investigation of the scheme is carried out and comparative analysis of the performance of the scheme is presented.
