Abstract
A power reception device includes a power reception antenna, a rectifier circuit, a communication section, a switch and a switch control section. The rectifier circuit converts electric power received by the power reception antenna into direct current voltage. The communication section communicates via the power reception antenna. The switch is connected between the power reception antenna and the communication section. The switch can transition between a conductive state where the communication section is electrically connected to the power reception antenna and a cut-off state where the communication section is electrically disconnected from the power reception antenna. The switch control section performs transition of the switch into the cut-off state when the direct current voltage exceeds a first threshold. The switch control section performs transition of the switch into the conductive state when the direct current voltage falls below a second threshold different from the first threshold.
