초록

본 논문에서는 직류 특성과 절전 모드에서 비절전 모드 변환과 같은 부하 변동 시의 동특성을 동시에 개선할 수 있는 가중치 전압 제어를 적용한 PC 전원용 다중출력 포워드 컨버터를 설계하였다. 기생성분을 포함한 전력회로를 모델링하고 소신호 해석하였으며, 가중치 결정 방법과 전압 보상회로 설계 방법을 제시하였다. SABER 시뮬레이션과 실험을 통해 제안한 방법이 PC 전원의 직류 특성과 동특성을 향상시킴을 입증하였다.

In this paper, the multiple output forward converter forPC power supply with weighted voltage mode control which improves the characteristics of DC and transient responses is analyzed and designed. The power stage model of this converter including all the major parasitic components is derived and the small signal model is also derived. Determination of the weighting factors and a design procedure for the loop compensation are presented. Finally, the proposed controller is verified through the simulation of three output forward converter with SABER, and the experiment.
