Webceptually, the circuit consists of the IGBT (device under test), a load inductor in the anode circuit, a voltage power supply to charge the inductor, and a pulse voltage source for the IGBT gate. The high-speed shunt protection circuit in the NET RB- SOA tester is a sophisticated vacuum tube-based circuit with a 2000 V, 100 A capability. WebThe IGBT is simulated as a series combination of a resistor Ron, inductor Lon, and a DC voltage source Vf in series with a switch controlled by a logical signal (g > 0 or g = 0). The IGBT turns on when the collector-emitter voltage is positive and greater than Vf and a positive signal is applied at the gate input (g > 0).
