1964E. K. Howell in IEEE Internat. Convention Record XII. ix. 86/2 To simplify the control of AC power, a completely new silicon semiconductor has been developed. ‘Triac’ is a generic term coined for this triode AC switch. 1975Hi-Fi Answers Feb. 78/2 The light pulses from the led are picked up by a photo-conductive cell, and applied to the..triggering circuit of the triac. 1981Computer-Aided Design Jan. 7/1 During the past two decades the application of triacs and thyristors in the control of power and machines with complex feedback arrangements has rapidly replaced the use of their conventional counterparts in almost all sectors of industry and public services. |
