Contactless electric power supply device
A contactless electric power supply device includes: a supply coil provided on a supply side device; a high frequency power source circuit that applies high frequency voltage to the supply coil; a receiver coil provided on a receiver side device that is arranged facing the supply side device, the receiver coil receiving high frequency electric power by contactless electric power supply via electromagnetic coupling with the supply coil; a receiver circuit that converts the high frequency electric power received by the receiver coil and supplies power to an electric load of the supply side device; and a supplementary coil provided on the supply side device, the supplementary coil interlinking with at least a portion of a magnetic circuit that electromagnetically couples the supply coil and the receiver coil.
