Power reception device, electronic apparatus, and non-contact power transmission system










Image Number 12 for United States Patent #8084991.

A power reception device includes a first resistance element having one end electrically connected to one end of a secondary coil which is able to be electromagnetically coupled to a primary coil of a power transmission devices a second resistance element having one end electrically connected to the other end of the first resistance element and having the other end supplied with a reference voltage, a power reception control device that obtains a frequency of an alternating current (AC) voltage induced on the secondary coil based on a voltage division signal output from the other end of the first resistance element and varies a magnitude of a load of the power reception device in accordance with the frequency, and a variable resistance element that has resistance varied in accordance with temperature and is connected to the first resistance element or the second resistance element in parallel.
