Classification: CPC G  H | IPC G  H

Claim 11:
12. A motor vehicle, comprising:
a direct current network;
a common communication bus;
two inverters each connected to the direct current network, wherein the two inverters each include:
a respective control unit connected to the common communication bus; and
a respective switching element which, in operation, is controlled by the control unit of the corresponding inverter with a clock signal; and

a further control unit connected to the common communication bus, wherein the further control unit, in operation, sends a message via the common communication bus at different times,
wherein the control unit of each of the two inverters, in operation, counts control operations carried out after synchronization of the clock signal controlling each of the two inverters,
wherein the control unit of a first one of the two inverters is a master control unit,
wherein the master control unit, in operation, transmits to the control unit of a second one of the two inverters at a point of time count information that describes the control operations counted at the point in time by the master control unit,
wherein the first one of the two inverters is different from the second one of the two inverters;
wherein the control unit of the second one of the two inverters, in operation, receives the count information, and
wherein the control unit of the second one of the two inverters, in operation, controls the switching element of the second one of the two inverters as a function of the count information and the control operations counted by the control unit of the second one of the two inverters.
