Modeling and Simulation of Three-phase Rectifier Based on SVPWM
The mathematical and simulation model of three-phase voltage source rectifier (VSR) used in aircraft is introduced in this paper. Based on the model, the principle of the seven-segment space vector pulse-with modulation (SVPWM) control strategy is presented. The double closed-loop control method is applied in the PWM rectifier. The rectifier can realize unity power factor by adopting the fixed switching frequency SVPWM current control method to realize that the current signal track voltage. The simulation results show that the mathematical model is accurate, and the SVPWM current control method can administer to improve the dynamic performance of three-phase rectifier obviously.
