WebJun 11, 2024 · Basically, household electricity is produced in waves that represent the voltage going up and down, and a leading edge dimmer regulates this fluctuation with something called a thyristor. A thyristor is like a gatekeeper that only allows electricity to pass through when the voltage is high enough. 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.

WebThyristor is a unidirectional semiconductor switch that conducts high current in on-state and blocks high voltages in off-state. It has three terminals Gate (G), Cathode (K) and Anode (A). The cathode and anode terminals are used to conduct the main current while the gate terminal switches the state of the thyristor. WebA “Triac” is another 4-layer, 3-terminal thyristor device similar to the SCR. It can be triggered into conduction in either direction. It has four possible triggering modes, of which 2 are preferred.
