Abstract(E) | Magnetic resonance wireless power transfer (WPT) is designed so that the resonance frequencies of the transmitter and receiver match well, but in practice, the resonance frequency mismatch occurs due to the parameter variations of the system components. In this paper, the efficiency characteristics of the WPT system with the resonance frequency mismatch are analyzed and a method for maximizing the efficiency is proposed according to the operating frequency setting. Furthermore, the efficiency characteristics are generally described using new parameter, resonance frequency mismatch coefficient, in addition to kQ product. The simulations and theoretical analysis verify that the maximum efficiency can be tracked by using the proposed optimum load resistance. |
