摘要

本論文主要的目的係在研製一具雙電源模組並聯之DC-DC 降壓型轉換器， 並加入所提之電流分配技術，以調控兩模組之輸出電流，使其輸出功率僅可能地 平均分配於各電源模組，用以改善只由單一模組供電之效率問題。於本論文中， 雙電源模組並聯型DC-DC 轉換器之規格為輸入電壓12V，輸出電壓5V，滿載輸 出電流20A。藉由理論推導、模擬及實作以驗證所提架構之可行性。

The main purpose of this thesis is to develop a DC-DC converter with two power
modules in parallel. With the proposed current-sharing strategy, the output current of
this converter can be distributed between two power modules as evenly as possible, so
as to enhance the efficiency as compared with the converter with a single module. In
this paper, the specifications for the proposed DC-DC converter with two power
modules in parallel are the input voltage of 12V, the output voltage of 5V and the
rated output current of 20A. The effectiveness of the proposed current-sharing scheme
is verified by means of theoretical derivation, simulation and experimental results.
