Abstract
A power semiconductor arrangement including conditional active clamping (CAC). One embodiment includes a power semiconductor arrangement. A controllable power semiconductor switch includes a load path. A driver unit for switching the load path to either an ON-state or an OFF-state. An active clamping (AC) unit configured to switch the load path in the ON-state if the voltage affecting the controllable power semiconductor switch is higher than or equal to an allowable voltage. A switching unit includes a control input, and configured to activate and/or to deactivate the AC unit dependent on a signal applied to the control input.
