TRIAC In this tutorial, we will learn about some of the basics of TRIAC. In the process, we will understand the structure, symbol, working, characteristics, applications of TRIAC. Introduction As we know that the SCR as a unidirectional device and has a reverse blocking characteristics that prevents the current flow in reverse biased condition. But for many applications, bidirectional control of current is required, particularly in AC circuits. To achieve this with SCRs, two SCRs must be connected in anti-parallel to control over both positive and negative half cycles of the input. However, this structure can be replaced by special semiconductor device known as a TRIAC to accomplish the bidirectional control. The TRIAC is a bidirectional switching device that can control the AC power efficiently and accurately. These are often used in motor speed controllers, AC circuits, pressure control systems, light dimmers and other AC control equipments. TRIAC Basics The triac is an i...
