Abstract
An electronic unit includes: an electricity reception section configured to receive power fed from a power feeding unit using a magnetic field; a voltage detection section configured to detect a received voltage supplied from the electricity reception section; and a control section, wherein while preliminary power feeding at a lower power than main power feeding is performed from the power feeding unit, and when a received voltage detected by the voltage detection section is equal to or higher than a predetermined threshold voltage, the control section performs voltage reduction control so as to decrease the received voltage to lower than the threshold voltage.
Claims12
An electronic device, comprising:
- electricity reception circuitry configured to wirelessly receive power fed from a power feeding device;
- a rectifier circuit configured to rectify the power supplied from the electricity reception circuitry;
- a load;
- a switching circuit coupled to the rectifier circuit and to the load;
- and
- a control circuit configured to control the switching circuit to be in an ON state or an OFF state,
- wherein during a preliminary power feeding that is at a lower power than a main power feeding performed from the power feeding device, the control circuit controls the switching circuit to be in the OFF state.
