WIRELESS POWER RECEPTION APPARATUS AND ELECTRONIC APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a wireless power reception apparatus capable of detecting a low feeding efficiency state resulting from a dislocation of a coil or proximity of foreign matter.SOLUTION: A rectifier circuit 10 rectifies an electric current Irunning through a reception coil L1. A smoothing capacitor C1 is connected with an output of the rectifier circuit 10. A discrimination section 20 generates a notice signal S1 corresponding to a comparison result between a voltage Vof a smoothing capacitor C1 at discrimination timing after starting reception of a signal from a power feeding apparatus and a predetermined threshold voltage V.
