초록

본 논문에서는 전원보드의 공통모드 노이즈 감쇠를 위한 디커플링 커패시터 회로를 효율적으로 시뮬레이션할 수 있는 구조분할 해석기법을 제시한다. 제시하는 구조분할 해석기법이 적용된 전원보드 설계에서는 보드를 두 부분으로 구조분할하였으며, 분할된 구조와 커패시터 회로의 임피던스 파라미터를 재결합하기 위한 방법을 제시하였다. 구조분할 해석기법을 적용함으로써 공통모드 노이즈 감쇠 시뮬레이션에 수행되는 시간을 46 % 이상 단축하였다.

In this paper, we present a design technique for the suppression of common-mode(CM) noise in switched-mode power supply boards using the segmentation method. By applying the segmentation method, the example structure is decomposed into two segments with decoupling capacitors and a recombination matrix is extracted for the segments. The effects of the decoupling capacitor on CM noise suppression are examined. The simulation time is significantly reduced on using the segmentation method.
