Abstract
Official abstract text for this publication.
A method for driving a controllable power semiconductor switch, having a first input terminal and first and second output terminals coupled to a voltage supply and a load, the first and second output terminals providing an output of the power semiconductor switch, includes adjusting a gradient of switch-off edges of an output current and an output voltage of the power semiconductor switch by a voltage source arrangement coupled to the input terminal. A gradient of switch-on edges of an output current and an output voltage is adjusted by a controllable current source arrangement that is coupled to the input terminal and generates a gate drive current. The profile of the gate drive current from one switching operation to a subsequent switching operation, beginning at a rise in the output current and ending at a decrease in the output voltage, is varied at most within a predefined tolerance band.
