臺灣博碩士論文加值系統

本論文主要研製一部應用於高壓電容測試之寬輸出電壓範圍直流電源供應器。功率級架構分為兩級，前級為降壓型轉換器，用以將輸出電壓轉換成後級電路所需輸入電壓；後級為全橋相移式串聯諧振轉換器，用以提供最大功率1kW/ 40V~6kV電壓輸出。控制方面使用德州儀器所開發的數位信號處理器晶片TMS320F28035以達成數位控制。論文內容包含主電路操作原理與設計考量，最後研製之雛型電路由實驗結果驗證其可行性。

This thesis mainly develops a high-voltage DC power supply with wide-range output voltage for high voltage capacitor test. The power stage consists of a buck DC-DC converter and a full-bridge SRC DC-DC converter. The pre-stage buck converter is operated to achieve the proposed voltage adjustment and provide the input voltage for post-stage converter. The post-stage circuit is a full-bridge phase-shifted series resonant converter, which provides 1kW rated power and a wide-range output voltage from 40V to 6kV. A DSP chip TMS320F28035 developed by Texas Instruments is adopted for realizing digital controller. In this thesis, the operation principles and design considerations for a prototype system were analyzed and discussed. Experimental results of the prototype converter are shown to verify the feasibility of the studied scheme.
