Provided is a method for controlling a contactless power supplying device (1) which supplies power by exciting a first coil (L1) and using an electromagnetic induction phenomenon in a second coil (L2) of a power receiving device (10) installed in an electric device (E). When the electric device is located on a mounting surface (3), The first coil (L1) is excited by a full bridge operation of a full bridge circuit (43a). When the electric device is not located on the mounting surface (3), the first coil (L1) is excited by a half bridge operation of the full bridge circuit (43a). [Reference numerals] (32) System control unit; (33) Non-volatile memory(Vk1, Vk2, Tk); (41) Reception circuit unit; (42) Signal extraction circuit; (43a) Full-bridge circuit; (43b) Driving circuit; (43c) Presence detection circuit; (44a) Oscillator circuit; (44b) Signal extraction circuit; (44c) Duty operation circuit |
