METHOD FOR CONTROLLING CONTACTLESS POWER SUPPLYING DEVICE AND CONTACTLESS POWER SUPPLYING DEVICE
First Claim
1. A method for controlling a contactless power supplying device that excites a primary coil and supplies power using an electromagnetic induction effect to a secondary coil of a power receiving device arranged in an electric appliance, the method comprising:
- full-bridge-operating a full-bridge circuit to excite the primary coil when the electric appliance is on a setting surface; and
half-bridge-operating the full-bridge circuit to excite the primary coil when the electric appliance is not on the setting surface.

Abstract
A method for controlling a contactless power supplying device that excites a primary coil and supplies power using an electromagnetic induction effect to a secondary coil of a power receiving device arranged in an electric appliance is provided. A full-bridge circuit is full-bridge-operated to excite the primary coil when the electric appliance is on a setting surface. The full-bridge circuit is half-bridge-operated to excite the primary coil when the electric appliance is not on the setting surface.

3. A contactless power supplying device that excites a primary coil and supplies power using an electromagnetic induction effect to a secondary coil of a power receiving device arranged in an electric appliance, the contactless power supplying device comprising:
-
a full-bridge circuit that is arranged in each of one or more power supplying areas defined in a setting surface on which the electric appliance is set and that excites and drives the primary coil; a detection circuit that detects whether or not an object is present on the setting surface and generates a detection signal; and a system control unit that drives and controls the full-bridge circuit, wherein the system control unit full-bridge-operates the full-bridge circuit to excite the primary coil when the detection signal indicates that the electric appliance is on the setting surface, and the system control unit half-bridge-operates the full-bridge circuit to excite the primary coil when the detection signal indicates that the electric appliance is not on the setting surface. - View Dependent Claims (4)
