Claim:
1. A DC/DC converter, comprising an active energy store having an inductance, a first controllable semiconductor switch configured to periodically charge the active energy store, and a second controllable semiconductor switch configured to periodically discharge the active energy store, with at least one of the first and second controllable semiconductor switches having an RCD element to prevent voltage overshoots for the at least one of the first and second controllable semiconductor switches, said RCD element comprising a capacitor and a diode connected in series and a resistor, and furthermore a switch having a first switching position connecting the resistor in parallel with the diode and a second switching position disconnecting the resistor from the diode, wherein the diode is arranged in series with the capacitor so as to be conducting in a direction of a current flowing from an emitter to a collector of the at least one of the first and second controllable semiconductor switches and to be blocking the current when the at least one of the first and second controllable semiconductor switches is conducting.
