本論文題目為應用於快充行動電源之數位升壓型轉換器研究與設計，內容詳細探討了升壓型轉換器其功率級架構與右半平面零點(Right-hlaf-plane zero)對於暫態行為的影響，並比較線性與非線性控制對於升壓型轉換器系統暫態之影響，得出非線性控制能跳脫系統頻寬之限制，減輕右半平面零點之影響。當系統遭遇負載變化時，本作品採用偏差限制控制技術(Fast and Deviation-Constrained Control)此數位非線性控制技術，以輕轉重載為例，開關全開直到電感電流達到新穩態值後，以變頻且固定工作周期操作為基礎的切換式升壓轉換器。透過保持一樣的工作周期(Duty Cycle)，可以改善傳統線性控制升壓轉換器受到系統右半平面零點影響，進而達到快速暫態回穩時間(recovery time)且能抑制系統之輸出電壓振福(Overshoot/Undershoot)。
本論文作品將此偏差限制控制技術結合傳統線性控制之升壓型轉換器，其保留線性控制的零穩態誤差且定頻操作的優點，並在暫態時，切換至暫態抑制迴路，限制輸出電壓振幅變化並快速回復到系統穩態，最後以FPGA搭配功率級板進行系統驗證與量測，證明透過此數位暫態抑制技術能大幅度改善系統的暫態性能，與傳統線性控制系統相比能加速85%回穩時間且能抑制輸出電壓振幅。

The topic of this thesis is the study and design of digital boost converter for quick-charging power bank applications. We introduce system architecture of power bank applications and power supply standard, then discuss the influence of the right half-plane zero(RHPZ) and the transient behavior of the boost converter in detail.
In order to reduce the RHPZ effect and conform to quick charge power supply standard. Therefore, this thesis collates many paper about fast transient and minimum output voltage deviation of analog and digital control. Analyze system control methods and compare advantages and disadvantages. It is concluded that the use of fast and deviation-constrained control technology can achieve an excellent improvement in transient effects compared to the usual traditional linear control.
According to this technology, this thesis combined linear and non-linear control in digital boost converter, which retains the advantages of zero-state error of linear control and switches to fast and deviation-constrained control in transient state to suppress output voltage amplitude variation and quickly return to system steady state. The overall architecture implementation requires only one voltage feedback ADC, which greatly reduces the hardware cost and the energy consumed. Finally, using FPGA as the experimental platform and performing system verification and measurement, it is proved that the control technology can greatly improve the transient performance of the system, and the performance is improved by 85% compared with the traditional linear control system.
