本論文旨在研究非接觸式感應充電系統，並提出一通用型可攜式產品充電平台。此充電平台係由數個Pot型鐵芯分為三組區域，利用感測線圈偵測其次級側感應結構於充電平台上之擺放位置，依據偵測結果開啟充電平台內之對應區域。當平台上置入多組電子負載時，系統設計之電源管理電路，即可針對負載獨立進行充電。系統中利用霍爾元件偵測初級側電感電流，經由單晶片控制電路調整系統操作頻率維持於初級側諧振頻率之上。此外，避免次級側偏移下無法接收足夠能量，利用感測線圈偵測之電壓回授，實現偏移保護機制。次級側感應結構則為一平面感應線圈配合平面型鐵芯建構而成，其整體厚度為2.35mm。最後藉由實測驗證非接觸式感應耦合結構，其於1mm氣隙下之最高電能傳輸效率達63.55%。

This thesis investigates the charging system based on contactless power transmission techniques for proposes a universal portable product charging platform. This platform is formed with several Pot-cores, and divided into three sections. The position of the secondary side induction structure on the charging platform can be detected by sensing coils, and according to detection result excites the localized charging platform. When several portable products are putted into platform, they can be charge independently by power management circuit. The system uses Hall component to sense primary inductance current, and via microchip control circuit to adjust operation frequency of system maintain on primary resonant frequency in charge platform. The system uses deviated protection structure to avoid receiving insufficient energy when the secondary side is deviated from the primary side. The secondary induction structure is established by planar induction coil and planar core that the thickness is 2.35mm. Experimental results show that the power transmission efficiency of contactless inductive structure is 63.55% under 1mm gap.
