SVPWM for 3-phase matrix converter driving an induction motor drive

this paper describes the implementation of 3-phase matrix converter using Space Vector Pulse Width Modulation (SVPWM) to control three phase induction motor. Variable AC output voltage engendered using matrix converter with bidirectional power switches controlled by appropriate switching pulse. The conventional PWM converter generates switching common mode voltage across the load system terminals, which cause to common mode current and its leads to bearing failure in load drive. These problems can be rectified using SVPWM and which minimize the effect on the harmonic fluctuation in AC output voltage and stress on the power switch is reduced using bidirectional switch for proposed 3-phase matrix converter. The simulation and experimental results have been presented to validate the proposed system using matlab / simulink and dsp-TMS320F2812 controller respectively
