Abstract
A method includes operating at least two inverters connected to a direct current network. Each inverter includes a control unit connected to a common communication bus and in each case at least one switching element, which is controlled by the control unit of the inverter with a clock signal. The common communication bus is connected to at least one further control unit, which in each case sends a message of a message type via the communication bus at different points of times. The reception of one of the messages of the message type in the control units of the inverters triggers a synchronization of their clock signals.
