In this video, I will basically explain the working principle of TRIAC. It used in home lighting, dimmer circuits, speed control circuits of fan motors and many power control systems including electronic switches which is one of the power electronic circuit elements. TRIAC is an improved version of the thyristor. While the thyristor can control large currents by operating in a single positive or negative alternator in AC, TRIAC can control large currents in both alternances of the AC waveform. In other words, while Thyristor is mostly used for DC power applications, we can say that TRIAC is more suitable for use in AC power applications. The abbreviation TRIAC comes from the initials of the English words Triode for Alternating Current. It is understood from its English name that this three-pin power electronics circuit element is used in alternating current.
