Title: POWER TRANSMISSION APPARATUS
Abstract:
Provided is a power transmission apparatus capable of efficiently transmitting power to a plurality of power receivers. This power transmission apparatus includes: a plurality of primary-side resonance coils, which are disposed along a transfer path of electronic apparatuses, and which transmit power, by means of magnetic resonance, to secondary-side resonance coils of the electronic apparatuses that are transferred along the transfer path; and a plurality of phase adjusting units, which are connected between an alternating current power supply and the primary-side resonance coils, and which adjust the phases of power supplied from the alternating current power supply to the primary-side resonance coils. The phase adjusting units adjust the phases of the power supplied to the primary-side resonance coils such that the phases of the power supplied from the alternating current power supply to the primary-side resonance coils match.
