Abstract
内容記述タイプ Abstract
内容記述 Wireless power transfer via magnetic resonant coupling method has open new possibility to electric vehicle (EVs) system. One is that it allows the wireless charging system of moving vehicles, using charging lanes. However, although the efficiency of power transmission is still relatively high, the efficiency still depends on the displacement of antennas. There have been several researches on methods to maintain power transmission at highest efficiency, such as impedance matching system or using control algorithm. However, in such systems, information on system parameter especially coupling coefficients is needed and in charging lane system, such information is unlikely to be obtainable without communication system which will add complexity to the system. Therefore it has come into attention that parameter estimation is the crucial factor to implement the charging lane system. In this study, coupling coefficient (k) estimation without using any communications between sending and receiving sides is proposed for wireless power transfer via magnetic resonant coupling. Theoretical estimation equations for k is proposed for both estimation from transmitting side and from receiving side, for both the system with single receiver and the system with multiple receivers. Coupling coefficient estimation system implementation is done for estimation from the receiving side using DC/DC converter. The estimation scheme based on statistical method such as recursive least square method taking errors caused by measurement error and hardware imperfection into consideration was studied to improve k estimation accuracy in actual system implementation.
