要約(英語): Wireless Power Transfer (WPT) of magnetic resonance coupling type can realize high-efficiency and high-power transmission. Recently, some studies have reported on the use of relay coils for controlling a system. Such a system shows complex resonance modes as it has many capacitors and coils. Therefore, the operating conditions depend on what a study focuses on. Additionally, almost studies have considered the system mathematically. There are few analyses that correspond to physical phenomena. In this study, we considered WPT in the resonance modes and transmission mechanisms on three coils. By using an original circuit derived from magnetic flux, two modes (Modes A and B) and energy transmission mechanisms were considered. The simulations and experiments show that the energy transmission mechanisms in the two modes are different. In mode A, the energy transmission from the power source to the load does not interfere with transmission field, whereas in mode B, it does.
