Title:
POWER TRANSMISSION DEVICE AND POWER TRANSMISSION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2013/077086
Kind Code:
A1
Abstract:
Provided are a power transmission device and power transmission control method capable of reducing standby power consumption while improving safety when no power reception device has been installed. A power transmission control means (1) causes a power circuit to supply a first voltage to a first active electrode when power is transmitted, (2) causes the power circuit to supply a second voltage lower than the first voltage to the first active electrode, and causes a power reception device detection means to sweep frequencies at a first time interval until the power reception device is installed, or (3) causes the power circuit to supply a fourth voltage lower than the first voltage to the first active electrode, and causes the power reception device detection means to sweep frequencies at a second time interval longer than the first time interval until the power reception device is removed.
