WebAug 18, 2024 · Thyristors are semiconductor equipment configured to function only in the switching function. Thyristor are current controlled products, a tiny Gate current is able to control a more substantial Anode current. Enables current only once forward biased and triggering current applied to the Gate. WebWhen designing and using thyristor or SCR circuits it helps to understand how the thyristor works. Essentially the operation of the thyristor / SCR can be explained in terms of a latching switch. Once tuned on by a current at the gate, it requires the voltage across the cathode and anode to be removed before it stops conducting.
