A circuit arrangement may include: an inverter comprising first electronic and second electronic switches coupled in series between a first and second input connections to form a bridge center point; a drive apparatus for the first electronic switch and the second electronic switch; a current-measuring apparatus which is designed and arranged to measure the current through the inverter; a short-circuiting apparatus which is designed to short-circuit the output when the output voltage exceeds a first predefinable threshold value; and an evaluation apparatus which is coupled to the current-measuring apparatus and is designed to determine the mean value of the current through the inverter and, when the mean value undershoots a second predefinable threshold value, to drive the drive apparatus in such a manner that the latter influences the operation of the inverter, by driving the electronic switches in such a manner that the current in the short-circuiting apparatus is reduced.
