Title:
POWER TRANSMISSION SYSTEM, TRANSMISSION DEVICE, AND RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/008671
Kind Code:
A1
Abstract:
This transmission device (1) is provided with: a pulse transformer (14a) having a primary winding connected to a PHY (13) and a secondary winding to which one end of a twisted pair wire (31a) is connected; a pulse transformer (14b) having a primary winding connected to the PHY (13) and a secondary winding to which one end of a twisted pair wire (31b) is connected; and an insulating DC/AC converter (12) that has a pair of output terminals (125, 126), one of which is connected to the center point of the secondary winding of the pulse transformer (14a) and the other of which is connected to the center point of the secondary winding of the pulse transformer (14b), and that converts a DC voltage into a pulse voltage. In addition, this reception device (1) is provided with: a pulse transformer (22a) having a primary winding to which the other end of the twisted pair wire (31a) is connected and a secondary winding connected to a PHY (23); a pulse transformer (22b) having a primary winding to which the other end of the twisted pair wire (31b) is connected and a secondary winding connected to the PHY (23); and an insulating AC/DC converter (24) that has a pair of input terminals (241, 242), one of which is connected to the center point of the primary winding of the pulse transformer (22a) and the other of which is connected to the center point of the primary winding of the pulse transformer (22b), and that converts an input pulse voltage into a DC voltage.
