Title:
POWER FEED DEVICE OF INDUCTIVE CHARGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/136753
Kind Code:
A1
Abstract:
A power feed device (2) of an inductive charging device (1) is provided with: a power factor correction circuit (10) that converts an AC power source into DC, and that corrects the power factor; a smoothing capacitor (16) that is connected to the output terminal of the power factor correction circuit; an inverter circuit (20) that has a plurality of switching elements (21, 23, 26, 28), and that generates an AC signal using the voltage of the smoothing capacitor as the power source; a power feed unit (9) that feeds power based on the AC signal to a power-receiving device (50); and a control circuit (6) that synchronizes at least one among the duty factor and the operating frequency of the switching elements in the inverter circuit with the AC power source and modulates the same.
