Abstract

Two existing continuous-time models for the current-mode control have presented noticeable differences in their small-signal predictions. As an attempt to clarify the origin of these disparities, this paper presents an alternative way of deriving a continuous-time model for the current-model control. The results of this paper would provide insights to comprehend the dissimilarity in the modeling method and final results of the earlier models of current-mode control models.

전류모드제어의 널리 알려진 두가지 연속시간모델이 소신호 예측에서 현저한 차이점을 보인다 따라서, 소신호에서의 불일치의 원인을 명백하게 하려고 한다. 본 논문에서는 전류모드제어를 위한 연속시간모델을 유도하는 다른 방안을 제시한다. 본 논문에서 제안한 전류모드제어모델과 기존의 전류모드제어모델과 모델링 방법의 차이점을 제시하고, 제안된 연속시간모델에 대한 타당성을 검증하기 위해 하드웨어실험과 PWM 블록의 모델에 샘플링효과를 포함하는 알고리즘을 제안하고, 전류루프이득을 시뮬레이션과 하드웨어 실험 결과와 비교, 검토하였다.
