Abstract

A duty cycle average model is mathematically developed for an average model of buck converter employing hysteresis c control. The derived model is able to simultaneously deal with both the continuous conduction mode (CCM) and the d discontinuous conduction mode (DCM) in the time domain. Also. taking advantage of the MAST language of SABER. a t template of the proposed duty cycle average model is built for the time and frequency domain analyses. The accuracy of t this template is verified through the computer simulations.

히스테리시스 제어를 사용하는 Buck 컨버터의 평균모델을 위한 Duty Cycle 모델이 수학적으로 구해진다. 이 모델은 시간영역에서 연속 전도 모드와 불연속 전도 모드 모두를 동시에 시물레이션할 수 있다. 또한, SABER의 MAST언어를 이용하여, 제안된 모델의 템플릿이 제시되며, 이 템플릿은 시간영역이나 주파수 영역의 해석을 위해 사용되어질 수 있다. 이 템플릿의 정확성을 컴퓨터 시뮬레이션을 통하여 증명한다.
