Abstract
Official abstract text for this publication.
This electrical power-receiving apparatus makes it possible to suppress a decline in power supply efficiency in a variety of different circumstances while avoiding an increase in circuit scale. This apparatus comprises an impedance control unit ( 307 ) for sequentially switching through any one of a plurality of charging devices in a charging device group ( 310 ), as candidate charging devices for a supply destination to which electrical power is to be supplied. The impedance control unit ( 307 ) also selects from the candidates a charging device to which electrical power is actually supplied, on the basis of the difference between the impedance of the charging device group ( 310 ) for each candidate and the impedance of an electrical power receiving antenna unit ( 301 ), and causes electrical power to be supplied to the selected charging device.
First claim
Opening claim text (preview).
