PROBLEM TO BE SOLVED: To provide size and weight reductions for a power receiving section by controlling electric power transmitted from a power feeding section to the power receiving section of a non-contact power supply unit on the feeding side, stabilizing the output voltage of the power receiving section without providing a voltage stabilizing circuit on the power receiving section, thus reducing the heating value of the power receiving section. SOLUTION: An input voltage detecting means for detecting the DC input voltage of the feeding section and a distance detecting means for detecting the distance between a feeding coil and a power receiving coil, intermittently control an inverter circuit. The power is not transmitted during a stopping period of the oscillation of the inverter circuit, therefore the power transmitted from the feeding section to the power receiving section is controlled corresponding to fluctuations of the DC input voltage in the inverter and of the distance between the feeding coil and the power receiving coil, so that the fluctuations of the power received at the power receiving section can be reduced. Thus, the fluctuations of the output voltage of the power receiving section can be reduced. COPYRIGHT: (C)2003,JPO
