Space Vector Pulse Width Modulation (SVPWM), one of the advanced computation based PWM techniques, has many advantages over conventional carrier-based PWM methodologies. Recently, with the easy availability of Microcontrollers and Digital Signal Processors, this technique is being widely used in industrial inverters. This paper presents a simple model for a three-phase two level SVPWM inverter using MATLAB-Simulink software. The entire model is based on only elementary Simulink blocks, and the use of advanced tool-box functions has been avoided. Hence, the model can be used, understood and modified easily as per the need of the user. The inverter has been divided into several sub-systems. Each such ‘sub-system-block’ is explained individually. Both linear and overmodulation-zone-controls have been included. The model operates successfully for various values of amplitude modulation index.
