This dissertation explores the design and implementation of a 6.78 MHz magnetic resonance coupling wireless power transfer (WPT) system. It covers the modeling and design of MHz high-frequency inverters, the design of reactive compensation networks, and the analysis of key performance metrics. The proposed system aims to enhance transmission efficiency while addressing safety and reliability concerns associated with traditional wired power systems. The research demonstrates significant improvements in power transfer efficiency and operational distance, with a particular emphasis on the advantages of using Class Φ2 inverters as well as the effectiveness of the SS-type compensation network. Experimental results indicate that the MRC-WPT system can achieve high efficiency and functionality in various applications, including consumer electronics and industrial uses.
