Abstract
A system includes an electronic device including a circuit having a semiconductor switch, and a controller configured to control a gate driver connected to the semiconductor switch via a protection circuit. The controller is configured to set a protection parameter including a voltage threshold representing a selected value of a voltage across the semiconductor switch, the protection parameter configured to cause the semiconductor switch to be deactivated in response to an overcurrent condition, the protection parameter selected based on a mathematical model of the semiconductor switch, the mathematical model representing a physical property of at least one of the electronic device and the semiconductor switch.
