Method for operating an electrical circuit arrangement comprising at least one first component and one second component, the electrical circuit arrangement, and a motor vehicle

An electrical circuit arrangement, comprising:

• a first component,
• a second component, and
• a control device,
• wherein the components are electrically connected across a direct current sub-grid of the electrical circuit arrangement,
• wherein the first component is switchable at a first operating point with a first cycle time and the second component is switchable at a second operating point with a second cycle time,
• wherein the components are connected across a communication link, and
• wherein the control device, in operation:
• switches the first component at a first operating point with a first cycle time;
• and
• switches the second component at a second operating point with a second cycle time,
• wherein a phase position is determined and set between the first cycle time and the second cycle time as a function of fault information describing at least one present alternating voltage in the direct current sub-grid, and
• wherein the fault information is determined as a function of the first operating point which has been set or is to be set or the second operating point which has been set or is to be set.
