DESIGN ANALYSIS AND IMPLEMENTATION OF SPACE VECTOR PULSE WIDTH MODULATING INVERTER USING DSP CONTROLLER FOR VECTOR CONTROLLED DRIVES

The space vector PWM (SVPWM) algorithm is implement ed using DSP controller to control the three-phase induction machines. SVPWM algorithm used in the experiment is simulated and the results are confirmed experimentally. Here, DSP processor computes the Voltage Space Vector and its components in (d, q) frame such as Vd, Vq, Vr ef, and angle ( α ).Also, it determines the switching time duration at any sector such as T1, T2, T0 and hence decides the switching time of each transistor (S1 to S6).SVPWM software parameters are observed and compared with the simulated ones. Also, the experimental outputs confirm the theoretical and simulation outputs. The different simulation and experimental results are observed and the analysis of the different results are presented.
