摘要： To provide a wireless power transmission system that is capable of efficiently transmitting power. The power transmitting device includes first and second electrodes (11, 12); first and second connection (15, 16) lines that electrically connect the first and second electrodes and an alternating current power generating section; and a first inductor (13, 14) that is interposed between the first and second electrodes and at least one of the two output terminals of the alternating current power generating section. The power receiving device includes third and fourth electrodes (21, 22) having a total width of a dimension of less than or equal to »/2À, which is a near field; third and fourth connection lines (25, 26) that electrically connect the third and fourth electrodes and a load; and a second inductor (23, 24) that is interposed between the third and fourth electrodes and at least one of the two input terminals of the load. A resonance frequency of a coupler including the first and second electrodes and the first inductor and a resonance frequency of a coupler including the third and fourth electrodes and the second inductor is configured to be substantially equal.

摘要： [OBJECT] There is provided a wireless power transmission system capable of transmitting power efficiently even when it is rotated. [ORGANIZATION] A power transmission device has a first and a second electrode (a center electrode 311 and an annular electrode 312) each having a rotationally symmetrical shape with respect to a common center axis, a first and a second connection line (connection lines 315, 316), and a first inductor (inductor 313, 314). A power reception device has a third and a fourth electrode (center electrode 321 and annular electrode 322) each having a rotationally symmetrical shape with respect to a common center axis, a third and a fourth connection line (connection lines 325, 326), and a second inductor. The electrodes of the power transmission device and the power reception device are disposed to oppose each other across a distance of »/2À or less as a near field, and a resonance frequency of a coupler constituted of the first and the second electrode and the first inductor and a resonance frequency of a coupler constituted of the third and the fourth electrode and the second inductor (inductor 323, 324) are set to be substantially equal.

摘要： [OBJECT] There is provided a wireless power transmission system capable of transmitting power efficiently even when there is an obstacle or the like. [ORGANIZATION] A power transmission device has a first and a second electrode (111, 112), a first and a second connection line (115, 116), and a first inductor (113, 114). A power reception device has a third and a fourth electrode (121, 122), a third and a fourth connection line (125, 126), and a second inductor (123, 124). At least one of the first to the fourth electrode is housed in a conductive casing (310, 320) having an opening corresponding to an opposing electrode, and a resonance frequency of a power transmission coupler constituted of the first and the second electrode and the first inductor (113, 144) and a resonance frequency of a power reception coupler constituted of the third and the fourth electrode and the second inductor (123, 124) are set to be substantially equal.
