摘要： A conventional circuit for blocking a semiconductor switching device (7) on overcurrent, the semiconductor switching device (7) having at least one continuously driven semiconductor switch (9), comprises a diver circuit (11), which has a driver stage (12) for each semiconductor switch (9), a control pulse generator (10) for producing control pulses (P1 to P6), which are fed in operation to a control input of the semiconductor switching device (7) via the driver circuit (11), and a monitoring device (34), which measures the current (I) flowing through the semiconductor switching device (7) and, when an overcurrent occurs, generates a fault signal (E), which initiates blocking of the semiconductor switching device (7). When the semiconductor switching device is being blocked, a high overvoltage can occur therein, possibly leading to destruction of the semiconductor switching device. In order to reduce, with little outlay, the overvoltage in the semiconductor switching device during blocking thereof, provision is made such that the operating voltage (U) of the driver circuit (11) is arranged to be switched over briefly by the fault signal to a lower, interim value corresponding to a lower current (I) through the semiconductor switching device (7) and then, within the maximum permissible duration for loading the semiconductor switching device (7) with an overcurrent, to be switched off completely.

摘要： A cooling apparatus for power semiconductors, which apparatus is essentially box-shaped, has two extruded cooling sections (14, 15) joined to each other. One of the cooling profiles (14) forms a first heat-conducting side wall (16), and the other cooling profile (15) forms a second heat-conducting side wall (17), opposite the first side wall (16), of the cooling apparatus (1). The side walls (16, 17) have cooling partitions (18, 19) formed on the inner sides of the latter, which cooling partitions bound cooling channels through which a cooling fluid can be conducted. Power semiconductors (4, 5) are to be attached to the outer sides of the side walls (16, 17) in a heat-conducting manner. In order to achieve the largest possible cooling surface of the cooling apparatus, the cooling partitions (18) formed on the first side wall (16) project between the cooling partitions (19) formed on the second side wall (17).
