本論文提出一個數位控制的非反向-升降壓兩用型轉換器，其架構具有大範圍的輸出電壓，可供應射頻電路功率放大器為求節能採用的可調操作電壓需求。針對此類電源轉換器在模式切換區間操作時，因導通週期不連續造成輸出電壓不穩定，本文進行了一連串詳細分析，並提出了一種全新的Duty-Locking控制概念，強制導通週期維持恆定並且藉由數位補償器的數值修正，消去輸出電壓和參考電壓之誤差訊號，讓補償器迴路和輸出電壓都能夠長時間保持在穩定操作，克服原本的缺點。將此控制架構搭配FPGA平台進行驗證，實驗結果也確實吻合理論推演。最後將驗證過的矽智財以TSMC 1P6M 0.18um Cell-Based製程下線，往電源控管系統積體化的目標邁進。

This thesis presents a digitally controlled Non-Inverting Buck-Boost Converter, its architecture has a wide range of output voltage, which can meet the requirement of Adjustable Operating Voltage for RF Power Amplifier to achieve the Energy-Saving goals. Due to the output unstable caused by Duty-Discontinuity region when Mode-Transition, the thesis displays a series of detailed analysis of Non-Inverting Buck-Boost Converter, and then proposes a brand new concept of Mode-Transition Technique, which is called Duty-Locking control. The new control method will force the Duty-Cycle to lock in a constant value, and eliminates the errors between output and reference signal by Reference-Fixing skill, ensures that both digital controller and output voltage can keep in stable for a very long time, overcomes the shortcomings of the original topology. Experiments the Duty-Locking control with FPGA platform for verification, also the results does consistent with the expectation of theoretical deduction. Finally, the proposed digital controller has been implemented in TSMC 1P6M 0.18μm CMOS technology, integrated Power Management system into ICs for future development.
