Abstract-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. Key words— power factor correction; SVPWM; Numerical simulation
I. INTRODUCTION
PWM rectifier is main technique applied in large unit power factor. Three phase PWM rectifier can be cataloged in voltage and current types, in which current type rectifier may employ many kinds of conventional PWM techniques, however, input line current is
discontinuous and output voltage ripple is much larger. While voltage type topology not only adopt many appropriate control strategies but also implements
bidirectional energy flow, and its main merit is that far dynamic response and simple configure. And
