Title:
NON-CONTACT POWER TRANSMISSION EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2014/030690
Kind Code:
A1
Abstract:
This non-contact power transmission equipment (10) is provided with: a power transmission device (11) having a primary coil (13a) into which AC power is inputted; a power receiving device (21) having a secondary coil (23a) capable of contactlessly receiving the AC power from the primary coil (13a), and a load (22) to which the AC power received by the secondary coil (23a) is inputted; a matching unit (31) provided in a first device, which is the power transmission device (11) or the power receiving device (21); a measurement unit (32) which measures the reflected wave power generable in the second device and which is provided in a second device, which is the other of the power transmission device (11) and the power receiving device (21) different from the first device where the matching unit (31) is provided; and control devices (14, 24) which, on the basis of the measurement results of the measurement unit (32), variably control a constant in the matching unit (31) such that the reflected wave power measured by the measurement unit (32) approaches 0.
