Real time digital simulation of PWM converter control for grid integration of renewable energy with enhanced power quality

A three phase full-bridge unity power factor converter is developed with the objectives to drain from the network a sinusoidal current on phase with the sinusoidal source voltage, which mean keeping the input power factor close to unity. A single-stage controller which combines Boosting, MPPT (Maximum Power Point Tracking) and DC/AC converter is developed in real time simulation with LabView and Matlab/Simulink. A method is presented to implement real time digital simulation with no hardware in the loop. It can get better effect in teaching or training of industry process control system with minimum cost. This paper develops a steady state model of DC/AC converter system in Space Vector Modulation (SVM) frame which take into consideration both effective real and reactive power control to improve power quality.
