Circuit configuration for supplying an electrical consumer and for limiting a time deviation of a switching current of a consumer

A method for limiting a time deviation dI/dt of a switching current of an electrical consumer with 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 whenever a value of a voltage change at said input terminals of said switching device exceeds a defined threshold value;
• and which comprises the following steps:
• detecting a value of an induction voltage brought about by current deviations dI/dt at said lead between said high supply potential and said switching device;
• and
• regulating at least one of the voltage and current supply of the electrical consumer in dependence upon the detected induction voltage for limiting the time-related current deviation dT/dt to a defined maximum value.
