Abstract
A circuit configuration for load-relieved switching has a bridge circuit with at least two controllable power switches, whose controlled paths are arranged in series with one another and between a first and a second supply potential. The circuit configuration has a drive circuit for driving the power switches, and an inductive element that is connected to output terminals of the bridge circuit. At least one power switch is designed as a field-effect-controllable, integrated transistor in accordance with the principle of charge carrier compensation or at least one power switch has deep pn junctions.
