Title:
無線電力伝送システム
Document Type and Number:
Japanese Patent JP7108181
Kind Code:
B2
Abstract:
To provide a system capable of improving the efficiency of wireless power transmission between a power transmission element and a power receiving element in a one-to-plurality, plurality-to-one, or plurality-to-plurality combination.SOLUTION: Based on four impedance matrices (Z, Z, Z, Z) determined based on a shape characteristic factor c, position p, and posture qof each power transmission element Tas well as a shape characteristic factor c, position p, and posture qof each power receiving element (R), M+N eigenvalues λ are obtained as solutions for an eigenvalue problem in accordance with a model in which a power transmission efficiency η from M power transmission elements Tto N power receiving elements Ris defined as a Rayleigh product. By variously changing an unknown designation factor, solutions for such a designation factor that a maximum eigenvalue λis maximized or made higher than or equal to a threshold value are retrieved.SELECTED DRAWING: Figure 1
