A drive circuit is provided for driving a voltage-driven semiconductor element by producing a drive signal depending upon an input signal. The drive circuit comprises an output stage and a current-suppressing circuit. The output stage includes two semiconductor elements connected in series. The voltage-driven semiconductor element is connected to a common connection point of the two semiconductor elements. The current-suppressing circuit controls one of the two semiconductor elements to provide an output current flowing through either one of the two semiconductor elements if a voltage applied to the voltage-driven semiconductor element reaches a limit level, which is in excess of a level for conducting the voltage-driven semiconductor element by a predetermined voltage.
