The circuit arrangement has multiple modules (M1,M2,M3,M4), in which drivers (3) are connected with a power semiconductor devices (2) over an electric line (4). A switching time circuit (5) is provided which is connected with the driver over another electric line (6). The switching signals (SA1,SA2,SA3,SA4) generated with the switching time circuit are so tuned to each other that a parameter controlling the switching time of the power semiconductor device is compensated and a simultaneous switching of the power semiconductor device is attained. An independent claim is also included for a method for operating a power semiconductor device.
