NON-CONTACT POWER FEEDING SYSTEM AND POWER RECEPTION DEVICE

In a non-contact power feeding system for transmitting/receiving power, by magnetic coupling, between a coil connected to a transmitting side DC/AC conversion circuit and a coil connected to a receiving side AC/DC conversion circuit so as to supply power from a power supply to a load, voltage control for the load is performed by the transmitting side DC/AC conversion circuit, and control of current that flows to a capacitor connected to an output side of the receiving side AC/DC conversion circuit is performed by the receiving side AC/DC conversion circuit. Accordingly, coil to coil efficiency in a case of low load can be enhanced without the need for any additional circuit.
