Title:
NON-CONTACT CHARGING SYSTEM POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/093423
Kind Code:
A1
Abstract:
Provided is a non-contact power supply device comprising: a power factor improvement circuit (3) which performs power factor improvement and outputs DC voltage; an electrolytic capacitor (18) which is connected with the output terminal of the power factor improvement circuit (3); an inverter circuit (4) which has a plurality of switching elements (19, 20, 24, 26) and generates an AC signal, using the voltage of the electrolytic capacitor (18) as a power source; a first resonance capacitor (6) and a first inductor (7) which are connected with the output terminal of the inverter circuit (4); and a power supply device control circuit (13). Furthermore, when power is supplied to a power-receiving device, the first inductor (7) is made to be opposite a second inductor (8) of the power-receiving device, and the power supply device control circuit (13) changes the current passage time and/or the drive frequency of the plurality of switching elements (19, 20, 24, 26) in accordance with the output of the inverter circuit (4).
