摘要:	本論文旨在研究可攜式電子產品無線功率傳輸系統技術改良，將市售可攜式無線功率傳輸電子產品進行線圈參數的量測，以及特性的分析，再利用線圈參數與特性，於期望頻率點進行補償電容的匹配，並將所得線圈參數與補償電容置於先進設計系統(Advanced Design System, ADS)進行模擬分析與驗證，以確保補償電路於期望頻率點達到共振的準確性，及整體無線功率傳輸架構的傳輸效果。最後藉由實測驗證，根據所需頻率點進行電容補償，可有效提升整體系統傳輸效率。;The purpose of this thesis is to design wireless power charging platform for diverse portable electronic products with different frequencies, so as to improving commercial wireless power chargers’ transmission efficiency. First, through measure the coils and analyze the equivalent circuit of magnetic resonance wireless power transmission system, the relationship between transmission efficiency and relevant parameters are derived. According to the required frequency, compensation capacitors are obtained by the principle of impedance matching. Then, use Advanced Design System (ADS) for simulations to ensure that the system performs at the required frequency. Finally, the system is implemented in experimental circuit to verify the overall system transmission efficiency can effectively uprate at same the resonant efficiency.
