Abstract
A control device for an inverter has a first inverter terminal, a second inverter terminal and a plurality of bridge branches, which bridge branches each comprise a first semiconductor, a winding terminal and a second semiconductor switch. The winding terminals are connected to a winding arrangement. The control device is configured to output a control signal which enables a first bridge branch state and a second bridge branch state in the case of at least two of the bridge branches in a first operating state, wherein, in the first bridge branch state, the second semiconductor switch assigned to the bridge branch is switched on, and wherein, in the second bridge branch state, the second semiconductor switch assigned to the bridge branch is switched off. At least two of the bridge branches are occasionally simultaneously in the first bridge branch state, and a change of said at least two bridge branches into the second bridge branch state is subsequently carried out at different points in time.
