Abstract

A space vector modulation scheme for the dual- inverter-fed open end winding induction motor drive, using only the instantaneous sampled reference voltages is presented in this paper. The proposed space vector PWM technique does not require the sector information and look-up tables to select the appropriate switching vectors for the two inverters. The inverter leg switching times are directly obtained from the instantaneous sampled reference voltage amplitudes and the inverter switching vectors are automatically generated. The proposed scheme ensures equal switching of the two inverters. The algorithm does not involve computations like square root and mapping of sectors. The proposed method is implemented on a 1-hp open-end winding induction motor drive and the results are presented.
