Abstract :
The author describes work being performed to manufacture, test, and characterize short-circuit proof IGBTs (insulated-gate bipolar transistors). These rugged devices can survive short circuit loads, which enable the power circuit to interrupt this current without blowing fuses. The devices are aimed specifically at the motor control market, where accidental load short circuits are common, but the devices should also find application in the power supply market. SCSOA (short circuit safe operating area) testing is described in detail.<>
