Triac Drehzahlregler Schaltplan. The triac is equivalent to two back to back scrs connected with one gate terminal as shown in figure. The triac is able to conduct in a number of ways more than the thyristor.

The triac structure is shown below and it can be seen that there are several areas of n type and p type material that form what is effectively a pair of back to back thyristors. When sw1 is closed gate current is applied to the triac from the battery supply v g via resistor r and the triac is driven into full conduction acting like a closed switch and full power is drawn by the lamp from. The circuit above shows a simple dc triggered triac power switching circuit.
Add an appropriately wired.
A triac is a bidirectional three terminal dual back to back thyristor scr switch. Triac variable power or dimmer. Simple triac switch circuit. The triac is a latching device which makes it ideal for pushbutton activation.
