A new software implementation of space vector PWM

The 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 the space vector modulation technique is generated using list of Matlab codes. The SimCoupler module provides interface between Matlab/Simulink and Psim software packages for co-simulation. The definite pattern for switching the voltage source inverter is provided using the software packages. The simulation study of the space vector modulation technique of the two level inverter reveals that the space vector modulation technique utilizes the DC bus voltage more efficiently and generates less harmonic distortion when compared with the SPWM technique. Simulation results are presented to demonstrate the validity of the space vector modulation technique.
