摘要

對於未來中央處理器的電源供應而言，可程式化的輸出電壓及其變化率會是一種重要的需求。在這篇論文中，極點配置法將被用於設計直流/直流轉換器的數位補償器，以完成上述的功能。相關的等式已推導完成，控制器也已由數位訊號處理器實現。此外狀態估測器亦被用於估測電感電流，以減少偵測電流之電路成本。此理論將由設計範例和實驗結果來驗證。

並列摘要

In future CPU power supply applications, there is a requirement of target voltage level programmability with certain slew rate specifications. In this thesis, pole-placement method will be used to design a digital compensator for a DC-DC converter for this purpose. Equations were developed and the controller was implemented with a DSP. A state estimator was also used to estimate the inductor current so that current sensing can be avoided. Examples will be given for the design and experimental results will be presented.
