| Zusammenfassung: | The utility model discloses a wireless power supply system. The wireless power supply system raises the charging efficiency, lowers temperature rise of a secondary side coil and the like, and carries out charging of a secondary cell efficiently. The wireless power supply system comprises an electric power sending section for sending electric power, and an electric power receiving section for receiving the electric power sent from the electric power sending section without contact and supplying electric power for a receiving side load. The electric power sending section has a power transmission coil generating a magnetic field according to an applied alternating voltage. The electric power receiving section has a power receiving coil generating an induced voltage according to the magnetic field generated by the power transmission coil through electromagnetic induction, a rectification section carrying out rectification and smoothing of the induced voltage generated by the power receiving coil and a voltage red |
