Claim Text:
1. A control circuit comprising: a controllable semiconductor component; and a circuit which indirectly limits a load current which flows through the controllable semiconductor component, the circuit comprising a voltage sensor for detecting a voltage between a first terminal of the controllable semiconductor component and a second terminal of the controllable semiconductor component, the voltage sensor being configured to output a value corresponding to the detected voltage, wherein the circuit is configured to control the controllable semiconductor component based on a value corresponding to a load-current-dependent power loss of the controllable semiconductor component, the load-current-dependent power loss being measured and/or calculated based at least in part on the outputted value corresponding to the detected voltage, and wherein the circuit is configured to minimize a total ohmic loss caused by charging a quantity of charge and a charging time for the quantity of charge.
