Modeling and simulation of three phase high power factor PWM rectifier

Numerical simulation methodology based on high frequency mathematical model of high power factor PWM rectifier is proposed in this paper. And input to output transform function is deduced. With the help of input to output transform function, the design method of voltage regulator has been presented. The simulation for three-phase PWM rectifier is implemented with Runge-kutta, thus comprehensive simulation can be achieved with M file in MATLAB. Finally, the simulation results and experimental results are given. The complete agreement with the results of simulation and experiment manifests that the proposed simulation method in this paper is effective. Of course, the design period of three-phase high power factor PWM rectifier can be shortened by virtue of proposed simulation methodology.
