An efficient approach for implementing Space Vector Modulation for controlling induction motor

Abstract

In induction motor speed control, from a DC voltage source, pulse width modulation (PWM) techniques generate variable AC voltages (both amplitude and frequency). Space vector pulse width modulation (SVPWM) utilizes DC bus voltage more efficiently with less harmonic distortion in a three-phase voltage source inverter. In the present work, an efficient approach for implementing SVPWM technique is developed reducing the computational burden. The control circuitry is realized using the microcontrollers (AT89C52). Experimental results are similar to the simulation results obtained by using PROTEUS VSM.
