Zusammenfassung: | In this paper, the reduced-order dynamic modeling and controller design of a push-pull DC-DC converter with current-mode control are presented. First, the small-signal equivalent circuit of the converter and its corresponding transfer function model are found. Then the selection of slope compensation and the model reduction are performed using the concept of dominant energy mode. Based on the reduced converter models, a quantitative design procedure is derived to find the parameters of the closed-loop controller such that the prescribed regulating specifications can be matched. Theoretic bases, the design and implementation of the proposed controller are described in detail. The performance of the converter and the validity of the proposed controller are demonstrated by some simulation and experimental results.< > |
