Abstract:
1. A driving circuit, which drives a power switching element while alternately setting the power switching element at an on state and an off state by applying a voltage to a conducting control terminal of the power switching element in response to an output pulse, comprising: a first switching element which sets a charging line at a conductive state in response to a first edge of the output pulse to supply an electric charge to the conducting control terminal of the power switching element through the first switching element and the charging line and to set the power switching element at one of the on and off states; a second switching element which sets a discharging line at a conductive state in response to a second edge of the output pulse to discharge the supplied electric charge from the conducting control terminal of the power switching element through the second switching element and the discharging line and to set the power switching element at the other state; and a current suppressing element which suppresses a through current flowing, in response to at least one of the first and second edges of the output pulse, through the first switching element and the second switching element.
