Title:
CONTACTLESS POWER FEEDING APPARATUS AND CONTACTLESS POWER FEEDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/020770
Kind Code:
A1
Abstract:
A contactless power feeding apparatus is provided with: a power feeding means for feeding power to a power receiving means in contactless state; a power-feeding side communicating means for executing wireless communication with a power-receiving side communicating means installed within the power receiving means; and a controlling means for setting power feeding conditions, including the amount of power to be supplied to the power receiving means, by conducting wireless communication with the power-receiving side communicating means, and implementing the power supplying to the power receiving means by driving the power feeding means according to the power feeding conditions. The controlling means sets the number of high-frequency signals to be contained in a power feeding signal to be generated by a power feeding signal generating means, such that the number of signals will become more the amount of power to be supplied to the power receiving means, which is one of the power feeding conditions, becomes greater. The controlling means also sets the modulation method to be used when a modulating means executes a phase modulation of high-frequency signals according to the set number of high-frequency signals.
