An electric circuit arrangement includes at least one half bridge including two power switching elements, two driver circuits, and a discharge control circuit, wherein the half bridge is in parallel with an energy accumulator and each power switching element has a switchable section with an electric resistance that is adjustable by a control voltage at a control input of the power switching element, while in a normal operation of the power switching elements, the drivers circuits generates the control voltage at the control input of each power switching element, and, while in at least one discharge operation that discharges the energy accumulator, the discharge control circuit generates a discharge voltage as the control voltage as the control input of at least one of the power switching elements, the discharge voltage placing the at least one of the power switching elements in linear operation.
