The simulation research of control modeling for three-phase voltage source SVPWM rectifier

On the basis of Discrete Control Modeling for Three-phase Voltage Source SVPWM Rectifier, the mathematical model of VSR and feed forward decoupling control technique were analyzed, the proposed SVPWM algorithm of matrix format can reduce amount of calculation. Basic SVPWM real-time controlling model was composed of four models including space sector determination model, acting time judgment model of correlation vector, calculation model of switch transit time and PWM model, which were constructed on the basis of high-speed signal processing system VHS-ADC of Lyrtech company in Canada. Focus on the research of system model simulation when change the load. This research demonstrate the validity, high-speed, stability. And this research made a foundation for ht further development of laboratory equipment.
