JEE_V1_N4_RP7 P. Parthiban Pramod Agarwal S.P. Srivastava Journal on Electrical Engineering 2230 – 7176 1 4 51 56 Current source inverter, Space vector modulation, Vector control, Induction motor In this paper duty ratio based space vector modulation for current source inverter fed induction motor drive is discussed. The control system of the induction motor is realized using direct vector control including field weakening region. Space vector modulation is the preferred PWM method for three phase current source inverters. A simplified SVM implementation that is based on calculation of duty ratio required to synthesize the reference current. The steady state and dynamic results of the proposed strategy are presented. The proposed scheme has the advantage of space vector modulation with fast dynamic response. April - June 2008 Copyright © 2008 i-manager publications.
