Webcarriers across all three junctions resulting in a large forward anode current. Once the SCR is switched on, the voltage drop across it is very small, typically 1 to 1.5V. The anode current is limited only by the external impedance present in the circuit. Fig.3.2: Simplified model of … WebJan 1, 2011 · The minimum anode current that will cause the device to remain in forward-conduction as it switches from forward-blocking is called the latching current I L. If the thyristor is already in forward-conduction and the anode current is reduced, the device can move its operating mode from forward-conduction back to forward-blocking. WebThe relationship between GTO thyristor anode current (IA) and cathode current (IK) is expressed by the following equa- tion: IA= IK+ IGQ To turn off the GTO thyristor, IBmust be smaller than IRB. The magnitude of the reverse-bias current IGQthat satisfies this condition can be calculated by the following equation: IGQ= (α1+ α2– 1) · IA/α1 tsb rewards account
