CONVERTER CIRCUIT FOR A TWO-VOLTAGE MOTOR VEHICLE NETWORK, TWO-VOLTAGE MOTOR VEHICLE NETWORK AND MOTOR VEHICLE

摘要

The invention relates to a converter circuit (14) for a two-voltage motor vehicle net- work (2), comprising a DC voltage converter (14.1) and a level shifter (14.2). In order to provide a converter circuit (14) for a two-voltage motor vehicle network (2) of a motor vehicle of a simple electrical design, said level shifter (14.2) is designed and configured as a bidirectional level shifter (14.2) and said pin BUS1 for the first communication network (8) is electrically conductive connected to said pin V1 for the first power supply network (4) by means of a first pull-up resistor R1 and said pin BUS2 for the second communication network (10) is electrically conductive connected to said pin V2 for the second power supply network (6) by means of a second pull-up resistor R3. The invention relates further to a two-voltage motor vehicle network (2) of a motor vehicle and a motor vehicle.
