Abstract
A non-contact power feeding device includes a power receiving element in a power receiving-side device, a power receiving circuit that converts power received by the power receiving element, generates a motive power voltage and outputs to a motive power load, and generates a control voltage and outputs to a control load, a power feeding element that is provided in a power feeding-side device, an power supply that switches between an operational frequency during driving of the motive power load and the control load and a standby frequency during driving of the control load only, and supplies power to the power feeding element, frequency detecting sections that detect a power reception frequency of the power received by the power receiving element, and a motive power shutoff section that shuts off output of the motive power voltage when the power reception frequency changes from the operational frequency to the standby frequency.
