A new software implementation of space vector PWM

Space Vector Modulation (SVM) Technique has become the most popular and important PWM technique for three phase Voltage Source Inverters for the control of AC Induction, Brushless DC, Switched Reluctance and Permanent Magnet Synchronous Motors. This paper proposes a new software implementation for Two Level Inverter using Space Vector Modulation technique. This software implementation is performed by combining Matlab and Psim software packages. The switching pattern generation and sector identification for space vector modulation technique is generated using list of Matlab codes. SimCoupler module provides interface between Matlab/Simulink and Psim software packages for cosimulation. The definite pattern for switching the voltage source inverter is provided using the software packages. The simulation study of space vector modulation technique of two level Inverter reveals that space vector modulation technique utilizes DC bus voltage more efficiently and generates less harmonic distortion when compared with SPWM technique. Simulation results are presented to demonstrate the validity of space vector modulation technique. ©2005 IEEE.
