Voltage Control by DQ Frame Technique of SVPWM AC- DC Converter

This article presents a simulation model of Space vector Pulse Width Modulation (SVPWM) Rectifier using MATLAB/Simulink which ability is to stabilize an output voltage of 500 Vdc from a 3 phase 300 V system using a decoupling feed-forward control method by dq frame technique. The model is tested due to a variation of ± 10% of rated input voltage. From the simulation model, it can use for implementation into a real-time control system by Digital Signal Processing Board (such as DS1104). Together, it also can be designed into a real circuit easily and effectively. The experimental results show that the SVPWM Rectifier which is presented in this paper has an adequate performance which can be applied widely
