摘要

本論文透過平板電腦、平板電腦基座與行動電源之間的結合想法，提出新型設計概念。文中將針對平板電腦基座的結合判斷、訊號切換架構、電源規劃、電源充放電時機、電路與印刷電路板佈局等設計面進行探討。
電源供電路徑的規劃分為平板電腦至平板電腦基座，與平板電腦基座至平板電腦兩大部分；將分別運用NVDC充電控制器、同步式升壓轉換器與線性穩壓器來完成此設計需求。平板電腦基座結合平板電腦的判斷機制與訊號切換時機設計，主要是透過嵌入式控制器來接收與判斷硬體電路上的電氣訊號準位，開啟對應的電源與訊號傳輸路徑，以達到平板電腦與平板電腦基座之間的溝通功能。
本論文設計透過實驗證明，平板電腦基座與平板電腦結合後，可以支援筆記型電腦與雙電池架構平板電腦之兩種使用情境。在平板電腦電池容量為7600mAh或8200mAh的1串聯2並聯鋰離子電池，以及平板電腦基座電池容量為2150mAh的2串聯1並聯鋰離子電池的規格條件下使用，透過MobileMark 2012 v1.5工具進行測試，平板電腦在單機測試與結合平板電腦基座後的組合測試結果來看，電池使用時間提升了近38%。

This thesis is to provide a new design concept through the connection of the Tablet-PC, the Tablet-PC Docking and the Power Bank. It is involved the discussion of the design of connection of the Tablet-PC and the Tablet-PC Docking, architecture of the signal switching, the power delivery, the timing of the charge and discharge of the battery, the schematics and the layout.
The power delivery path is divided in two major portions. One is from the Tablet-PC to the Tablet-PC Docking and the other is the Tablet-PC Docking to the Tablet-PC. It is required the NVDC Charge Controller, the Synchronous Boost Converter and the Linear Low Dropout Voltage Regulator for the design. The Embedded Controller receive the signal of the hardware corresponded to the power and the signal path accordingly. It is the communication method for making judgment of the connection and the signal switching timing when the Tablet-PC and the Tablet-PC Docking inserted.
This thesis is approved by the experiment. It supports 2 user scenarios of the Notebook and the dual battery Tablet-PC when Tablet-PC connected to Tablet-PC Docking. The capacity of Li-ion battery of the Tablet-PC is 7600mAh or 8200mAh in one series and two parallel connection. The capacity of Li-ion battery of the Tablet-PC Docking is 2150 mAh in two series and one parallel connection. The battery usage period when the Tablet-PC connected to the Tablet-PC Docking is improved 38% which is verified by MobileMark 2012 v1.5 compared to Tablet-PC only.
