WebCh1: gate-emitter voltage 5 V/div, Ch2: PWM signal from controller 5 V/div, Ch 3: collector-emitter voltage 100 V/div; 200 ns/div. Summary. Overcurrent and short-circuit detection and turn-off in a very short time period are becoming ever more important as the short-circuit withstand time of IGBT decreases down to 1 μs levels. WebAn insulated gate bipolar transistor is simply turned “ON” or “OFF” by activating and deactivating its Gate terminal. Applying a positive input voltage signal across the Gate and the Emitter will keep the device in its “ON” state, while making the input gate signal zero or slightly negative will cause it to turn “OFF” in much the same way as a bipolar transistor …
