Abstract:
1. A circuit configuration, comprising: a power semiconductor component having load connections including a first load connection and a second load connection; a connecting line connected between one of said load connections and one of a load and a terminal for a supply potential, said connecting line having a given resistance; said connecting line defining a first node and a second node, said first node being common to one of said load connections and said connecting line, said second node being remote from said power semiconductor component; a measuring configuration having a first terminal and a second terminal as input terminals, said first terminal of said measuring configuration being connected to said first node, said second terminal of said measuring configuration being connected to said second node of said connecting line; said measuring configuration further having a series circuit including a first resistor and a second resistor, said first resistor having a resistance, said given resistance of said connecting line and said resistance of said first resistor having a given ratio, said second resistor being a variable resistor; said terminal for a supply potential supplying a first supply potential; and said series circuit connected between a second supply potential and said second terminal of said measuring configuration.
