摘要:	本論文旨在設計無線功率傳輸系統之線圈與鐵氧體，首先透過磁共振式無線功率傳輸之等效電路，推得傳輸效率與各參數的關係，加上分析線圈參數對傳輸效能的影響，接續進行線圈設計，再利用電磁模擬軟體(Maxwell)及先進設計系統(ADS)進行模擬分析和驗證，以確認線圈之間的傳輸效果。根據推論可得知加裝鐵氧體的必要性，可以有效限制磁力線的範圍、減少漏磁、降低電磁干擾，最後根據無線功率傳輸的使用需求進行鐵氧體形狀的設計，使得傳輸效率可以有效提升。;The purpose of this paper is to design coils and ferrites for wireless power transmission system. First, through the equivalent circuit of magnetic resonance wireless power transmission, the relationship between transmission efficiency and various parameters are derived, and analyze the influence of the coil’s parameters on transmission performance. Continue to design the coils, use electromagnetic simulation software (Maxwell) and Advanced Design System (ADS) for simulations and verifications, and confirm the transmission efficiency between the coils afterwards. According to the inference, it can be known that the necessity of installing the ferrites, it can effectively limit the range of magnetic flux, reduce magnetic flux leakage and reduce electromagnetic interference. Finally, design the ferrite shapes according to the usage requirements of wireless power transmission so that the transmission efficiency can be improve effectively.
