Title:
CONTACTLESS POWER TRANSFER APPARATUS, POWER TRANSMISSION DEVICE, AND POWER RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/064361
Kind Code:
A1
Abstract:
The present invention is a contactless power transfer apparatus which enables a power value to be inputted to a load to approach a target value.
This contactless power transfer apparatus is provided with: an alternating-current power supply (12) which outputs alternating-current power and is able to change the power value of the alternating-current power; a primary coil (13a) to which the alternating-current power is inputted; a secondary coil (23a) which is able to receive the alternating-current power inputted to the primary coil in a contactless manner; a load; a secondary measurement unit (25) which measures a power value at a predetermined position on a power transfer path through which power is transferred from the secondary coil to the load; and a power supply control unit (15). The power supply control unit (15) controls the alternating-current power supply such that when the power value measured by the secondary measurement unit is smaller than a specific value, the power value of the alternating-current power to be outputted from the alternating-current power supply becomes larger within a range less than or equal to a predetermined upper limit. The specific value is defined as a power value at the predetermined position when a power value to be inputted to the load becomes a target value.
