Space Vector Pulse Width Modulation Schemes for Two-Level Voltage Source Inverter

method is an advanced, computation intensive PWM method and possibly the best among all the PWM techniques for variable frequency drive applications. The SVPWM is an alternative method for the determination of switching pulse width and their position. The major advantage of SVPWM stem from the fact that, there is a degree of freedom of space vector placement in a switching cycle. This feature improves the harmonic performance of this method. This method has been finding widespread application in recent years because of the easier digital realization and better dc bus utilization. In this paper, three SVPWM schemes, called 7-segment space vector modulation (SVM), 7-segment SVM with even-order harmonic elimination and 5-segment (discontinuous) SVM are studied in detail. The theoretical analysis, design, switching sequence and SIMULINK implementation of these three SVM schemes is presented in step-by-step manner
