In particular, the control device can also be designed to reduce the voltage between the terminals after a further predetermined time interval, from the second value to a third value which is lower than the second value.

The half-bridge preferably comprises a first current control valve for connecting the first terminal to a high potential of an intermediate circuit voltage and a second current control valve for connecting the first terminal to a low potential of the intermediate circuit voltage. In this case the control device is preferably designed to actuate the current control valves alternately in order to set the predetermined voltage. Together with a control logic the half-bridge can be integrated in one assembly. For example, the control logic can adjust or regulate the voltage as a function of a specification, carry out a dead-time compensation for the current control valves or detect a defect situation such as a short-circuit of one of the terminals to one of the potentials. In an embodiment, a plurality of half-bridges are integrated with one another in one component. For example, two or three half-bridges can be provided and the component can be designed to control a direct-current motor or a brushless electric motor.
