Abstract

A system to detect a status of a switching semiconductor in a switching circuit is provided. The system includes the switching semiconductor, an actuator, wherein the actuator is electrically coupled to a first end of the switching semiconductor, a resistor electrically coupled to a second end of the switching semiconductor, a switching device electrically coupled to the resistor, a detector connected to a collector terminal of the bi-polar junction transistor, and a processor. The processor is configured to provide a trigger voltage to the switching semiconductor, wherein the trigger voltage activates the switching semiconductor and induces current flow from the actuator through the resistor via the switching semiconductor. The processor activates the switching device, based on the activated switching semiconductor and detects a voltage at a collector terminal of the switching device. The processor determines the status of the switching semiconductor based on the detected voltage.
