WebDescription. Triacs are three-terminal silicon devices that are configured in an inverse parallel arrangement to provide load current during both halves of the AC supply voltage. They have two anodes (A1 and A2) for conducting current in both directions. They also have two gates (G1 and G2), each of which triggers a corresponding anode. WebSep 16, 2009 · Triac Applications. 1. High Power Lamp Switching. Use of the triac as an ac on/off switch is shown in figure. When the switch S is in position 1, the triac is cut-off and so the lamp-is’dark. When the switch is put in position 2, a small gate current flowing through the gate turns the triac on and so the lamp is switched on to give rated output. lapinlahti kunta

WebA TRIAC acts much like two SCRs connected back-to-back for bidirectional (AC) operation. TRIAC controls are more often seen in simple, low-power circuits than complex, high-power circuits. In large power control circuits, multiple SCRs tend to be favored. When used to control AC power to a load, TRIACs are often accompanied by DIACs connected ... Webneeds to be considered is the TRIAC, which is a bi-directional AC switch. If one understands the characteristics and functionality of an SCR, a TRIAC can be thought of as two back-to-back SCRs with a common gate. This structure allows current to flow in both polarities and thereby constitutes a highly effective AC switch. Fig. 8
