本論文旨在設計及研製一全橋升壓型DC/DC電力轉換器，目的是為了穩定負載直流端電壓及有效地將功率傳送至負載。然而燃料電池本身之輸出電壓容易受到負載變動及燃料電池極化損失的影響，而造成直流輸出端電壓不穩定。因此本論文利用間接型滑動模式控制法則以穩定系統之輸出電壓。本文分成三部份：首先探討燃料電池的基本特性以做為轉換器設計之參考基準，第二部份則針對DC/DC轉換器切換技術及控制法則加以探討，第三部分整合DC/DC轉換器與燃料電池發電模組來建構一完整的系統，並測試其運作效能。
本論文已建立以DC/DC轉換器之燃料電池發電系統雛型，並以高效能之數位訊號處理器作為控制核心，以減少硬體電路的元件。最後完成775W的實體系統，並由實驗測試結果加以驗證分析。

This thesis presents a method of design and implementation for a full-bridge DC/DC boost converter to hold DC bus constantly and to translate power to load effectively. Because the voltage of a fuel cell system is easily affected by the load variations and polarization loss, indirect sliding mode control algorithm is developed to stabilize DC bus voltage. This thesis is composed of three parts: the first part focuses on the basic characteristic of the fuel cell system in order to provide guideline for power converter design. The second part aims at the DC/DC converter switching techniques and control rules. The third part integrates the system with a DC/DC converter and fuel cell generation module. The performance and efficiency of the system are measured.
In this thesis, a model of DC/DC power converter with the fuel cell generation system was constructed. A high performance digital signal processor was used to implement the system to reduce circuit design. The experimental results on a 775W prototype system were provided to verify the analysis and performance of the system.
