Self-consistent … Webb10 jan. 2024 · The SCR is a unidirectional device that allows the current to flow in one direction and opposes it in another direction. SCR has three terminals namely Anode (A), Cathode (K) and gate (G), it can be turned ON or OFF by controlling the biasing conditions or the gate input. Again the Thyristor symbol and SCR symbol are the same.
