NON-CONTACT POWER TRANSMISSION DEVICE AND POWER-RECEIVING APPARATUS

摘要

A non-contact power transmission device (10) is provided with: an AC power source (12, 52); a primary-side resonator (13) having a primary-side coil (13a) and a primary-side capacitor (13b); a secondary-side resonator (23) having a secondary-side coil (23a) and a secondary-side capacitor (23b) and being capable of receiving AC power from the primary-side resonator (13) in a non-contact manner; a rectification unit (24) for rectifying AC power received by the secondary-side resonator (23); a power storage unit (22) to which DC power rectified by the rectification unit (24) is inputted; and a control unit (26) for variably controlling the inductance of the secondary-side coil (23a) and/or the capacitance of the secondary-side capacitor (23b) to thereby ensure that DC power having a power value suitable for charging is inputted to the storage unit (22).
