Abstract
Abstract A circuit configuration includes a first electronic reversing switch having an output being superimposed on a first operating potential during a first switching phase and on a second operating potential during a second switching phase, as well as a second electronic reversing switch having an output being superimposed on the first operating potential during the first switching phase and on a node point during the second switching phase. A diode is connected in the conducting direction between the second operating potential and the node point. A capacitor is connected between the output of the first electronic reversing switch and the node point.
