thyristor revere connection with gate
When a positive voltage is applied at thyristor negative terminal and a negative voltage is applied at positive terminal of thyristor at that time the thyristor is in reverse baise.When a positive gate is applied at the thyristor reverse baise condition,at that time P and N+ are in forward baise and the N- and P+ are in reverse baise then the total reverse voltage is appears across the reverse baise layer at that time the juction temperature is very high and thermal run away appears and thyristor is damaged.
ANSWER: damaged
