Abstract
Disclosed is a non-contact power supply system wherein power is transmitted by means of a magnetic field resonance method from a power transmission device, which includes a power transmission-side resonant circuit, to a power reception device, which includes a power reception-side resonant circuit. The power transmission device detects, at the time of transmitting the power, a load in the power transmission, and stops the power transmission in the cases where a detection result deviates from a specified normal range. In the power reception device, a power stabilization circuit () that maintains output power of the power reception circuit constant is provided between a load circuit () and a power reception circuit () that outputs, toward the load circuit, power on the basis of power received by the power reception-side resonant circuit.
