POWER RECEPTION APPARATUS AND ELECTRONIC APPARATUS

摘要

This power reception apparatus is provided with a non-contact power reception antenna, a power supply unit, a communication antenna, a communication unit that performs communication via the communication antenna, a communication switch, and a switch control unit. The power supply unit outputs an output voltage corresponding to power received via the power reception antenna. The communication switch can transit between an electrically connected state wherein the communication unit is electrically connected to the communication antenna, and a disconnected state wherein the communication unit is disconnected from the communication antenna. The switch control unit makes the communication switch transit to the disconnected state when the output voltage of the power supply unit is increased over a first voltage, and the switch control unit makes the communication switch transit to the electrically connected state when the output voltage is reduced to below a second voltage that is lower than the first voltage.

主权项

1. A power reception device comprising:
a power reception antenna which receives electric power in a non-contact manner; a power supply section which is connected with the power reception antenna and outputs an output voltage depending on electric power received via the power reception antenna; a communication antenna; a communication section which makes communication via the communication antenna; a communication switch which is connected between the communication antenna and the communication section and is switchable between an electrically connected state where the communication section is electrically connected with the communication antenna and an electrically disconnected state where the communication section is electrically disconnected from the communication antenna; a switch control section which is connected with the power supply section and performs control to switch the communication switch between the electrically connected state and the electrically disconnected state, wherein the switch control section switches the communication switch into the electrically disconnected state when the output voltage increases above a first voltage, and switches the communication switch into the electrically connected state when the output voltage decreases below a second voltage smaller than the first voltage.
