초록

본 논문에서는 불연속 인덕터 전류모드에서의 다상 교호 강압 컨버터의 정상상태 해석 및 소신호 모델을 유도하여 일반화된 식을 제시한다. 컨버터의 제어기 설계를 위해서 필요한 완전한 차수 모델을 통한 소신호 모델의 전달함수를 유도하고 이를 통해 시스템의 동특성을 분석한다. 시뮬레이션 및 실험 결과를 통하여 이론에서 제시한 특성을 검증한다.

This paper presents the generalized and explicit expressions for evaluating the performance of the multi-phase interleaved buck converter (IBC) operating in discontinuous inductor current mode (DICM). The full-order averaged model is derived. The generalized transfer functions of interest are presented and the dynamic characteristics are analyzed. The generalized analysis of converter performance is verified through the experimental and simulation results.
