The Study of PFC Converter added Active DC Filter Using for the Predict Current Control Method

예측 전류 제어기법을 사용한 능동 DC 필터 부가형 PFC 컨버터에 관한 연구

In this paper, we firstly proposed to the boost type PFC circuit for a power factor improving and a harmonic decreasing. The predict current control method is used to control these PFC circuit. This current control method has a merit that is possible to improve power factor and harmonics. In addition, we suggested to the active DC filter, which is connected with the DC output terminal, in order to compensate the DC ripple components. Consequently, these results are proved by the simulation tool, PSIM, which is an exclusive simulator of power electronics.
