TRIAC

TRIAC (Triode AC switch) is characterized as a three-terminal silicon device that functions as two SCRs configured in an inverse, parallel arrangement, providing a means of providing load current during both halves of the AC supply voltage.

A TRIAC is generally used for motor speed control. Since load current (armature current) flows during both halves of the applied AC voltage, the motor rotates smoothly at all rotational speeds
