WebIt cannot switch off unless (a) the forward voltage is removed or (b) the current through the thyristor decreases then a level known as ‘holding current’. A thyristor is a latching device. When it is triggered using gate input, the device remains latched in on-state. It does not need the continuous gate supply to remain in the conduction state.
WebThyristor Commutation refers to the process of turning the thyristor off. There are several ways utilizing which the thyristor gets commutated which is known as thyristor commutation techniques. We know that once a thyristor gets turned on after the application of gate pulse then even after the removal of gate pulse, current continues to … WebTo turn off the GTO thyristor, I B must be smaller than I RB. The magnitude of the reverse-bias current IGQ that satisfies this condition can be calculated by the following equation: …
