How do you turn on a silicon controlled rectifier? |
[Improve]
In the usual circuit, a pulse of voltage on the gate electrode, providing a very small current, will cause a large current to flow from anode to cathode. The SCR will stay on until the anode current is reduced to zero (which may be because it's an AC supply).
