This abstract first appeared for US patent application 18730510 titled 'Electronic Circuit Arrangement for Current Limitation
Original Abstract Submitted
An electronic circuit arrangement for current limitation in a load circuit includes a power semiconductor located between a supply voltage and a load, wherein the control input of the power semiconductor is connected to the output of a controller stage and a switching contact of a circuit breaker, where a shunt resistor is inserted into the load and the voltage occurring there increases the voltage potential at the control input of the circuit breaker, a current source is also connected to the control input of the circuit breaker, where the current source generates a bias voltage at the control input of the circuit breaker via a series resistor, and where the current source has a negative temperature coefficient.
