Title:
POWER TRANSMISSION DEVICE AND NON-CONTACT POWER TRANSMISSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/146605
Kind Code:
A1
Abstract:
This power transmission device is provided with an alternating current power supply, primary-side coil, control unit, control power supply, and switching unit. The alternating current power supply has: a first conversion unit that converts external power into first direct current power; and a second conversion unit that outputs power by converting direct current power into alternating current power at a predetermined frequency. The second conversion unit outputs, as alternating current power, first alternating current power in the cases where the first direct current power is inputted from the first conversion unit, and outputs, as alternating current power, a second alternating current power having a power value smaller than that of the first alternating current power in the cases where second direct current power is inputted from the control power supply.
