Abstract:
A circuit configuration for supplying at least one of switchable voltage and current to an electrical consumer, comprising:a switching device having input terminals; a voltage source having at least two output terminals for tapping at least one high and one low supply potential; a driver circuit connected to said input terminals of said switching device for driving said switching device; at least one lead connected between said output terminals of said voltage source and said input terminals of said switching device; at least one leakage inductance distributed to said at least one lead; a measuring and evaluating circuit for detecting voltage deviations at said input terminals of said driver circuit arising from current deviations in said at least one leakage inductance of said at least one lead, and for evaluating said current deviations; and a feedback circuit for controlling feedback of said driver circuit to slow switching processes of said switching device by reducing time deviations of the switching current whenever a value of a voltage change measured by the measuring and evaluating circuit exceeds a defined threshold value.
