Abstract: 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.

Abstract: The invention relates to a purge pump system (1) of a vehicle (2) for purging C-H-gas of a tank system (3) to an induction line (4) of a combustion engine (5) of the vehicle (2), comprising a purge pump (6) and gas connection lines (7) for connecting the purge pump (6) with the tank system (3) and the induction line (4), wherein the purge pump system (1) further comprises a brushless DC motor (8) and a control unit (9), wherein the brushless DC motor (8) comprises a rotor and a stator, wherein the control unit (9) is configured for providing the brushless DC motor (8) with a commutative current to effect a relative rotation of the rotor to the stator. The purge pump system (1) further comprises a shutdown unit (10) for receiving an enable-signal of the vehicle (2) via an enable signal line (11), wherein the shutdown unit (10) is configured to short-circuit the brushless DC motor (8) as a response to a loss of the enable signal. The invention further relates to a vehicle (2) and a method for operating a purge pump system (1) of a vehicle (2) according to the invention.
