Abstract

In this paper, several control methods for the discontinuous mode PWlvl-SRC are investigated with the l linearized small signal model. In order to analyze the stability and dyncunic characteristics of the controlled s system, the root locus as a function of the normaliz떠 output current(]\iOC) for a given normalized output v voltage(NOV) is employed. FurLhem10re, in this paper, the “Optimal trajectory control of PWM-SRC" is newly p propos(xl and its good dvnamic performances are evaluated with other four control laws.laws.

본 연구에서는 선형화 소신호 모델을 이용하여 불연속 모드 펄스폭 공진회로의 다양한 제어방법에 대하여 조사 하였다. 각 제어방식에 따른 시스템의 안정도와 동적 특성을 분석하기 위하여 정규화 출력 전류와 전압을 사용한 근궤적을 나타내었다. 또한, 최적의 궤적 특성을 가지는 제어기를 새로이 제안하였으며, 이러한 제어의 우수한 특성을 다른 형태의 제어방식과 비교함으로써 입증하였다.
