Title: NON-CONTACT POWER SUPPLY APPARATUS
Abstract:
This non-contact power supply apparatus, which supplies power to a power reception coil (21) in a non-contact manner by means of at least magnetic operations, is provided with: a plurality of power transmission coils (11a-11c), which have different coil surface areas, while having coil surfaces thereof disposed at positions parallel to each other; a power reception coil detection means that detects the power reception coil (21); and a control means, which, on the basis of detection results obtained from the power reception coil detection means, controls power to be outputted to a magnetizing coil from the power supply. The control means selects, as the magnetizing coil, a coil to be magnetized, from among the power transmission coils (11a-11c) corresponding to a coil surface area of the power reception coil (21), and distances between the power reception coil (21) and the power transmission coils (11a-11c).
