Reactive Current Control Method for Variable Source Voltage of AC-DC PWM Converter

무효전류 제어기법에 의한 전원전압 보상형 컨버어터의 구성에 관한 연구

In this paper a control method to compensate the fluctuation in source voltage by using reactive current is presented. When the source voltage is changed within $\pm$10[%] range, the unit power factor is carried out. Otherwise, the converter is controlled by variable power factor. By using above control, the converter input voltage is maintained constantly. And then it was certified by simulation with the ACSL and several experiments.
