TRIAC
We know that a unidirectional device like a SCR incorporates the characteristics of the reverse blocking current since it stops the progression of current in a reverse-biased state however for a few applications, this sort of current control is essential, particularly in AC circuits. So this can be accomplished through SCRs, where the association of two SCRs ought to be finished in enemy of lined up for controlling over both positive as well as bad information half cycles. However, this game plan can be changed through a unique semiconductor device called TRIAC, used to accomplish bidirectional control. This device controls the air conditioner unequivocally and every now and again utilized in controlling the speed of the engine, AC control devices, AC circuits, light dimmers, pressure control systems, and so on.
