Triac Characteristics

quick overview :

Object: 1. To study the gate characteristics of a TRIAC in the following modes : (a) Mode I+ : i.e. T2 positive with respect to T1 and gate positive with respect to T 1 (b) Mode I- : i.e. T2 positive with respect to T1 and gate negative with respect to T 1 (c) Mode III+ : i.e.T2 negative with respect to T1 and gate positive with respect to T 1 (d) Mode III- : i.e. T2 negative with respect to T1 and gate negative with respect to T 1 2. To study the terminal characteristics of a TRIAC in the following modes : (a) Mode I+ : i.e. T2 positive with respect to T1 and gate positive with respect to T 1 (b) Mode III+ : i.e. T2 negative with respect to T1 and gate positive with respect to T 1 3. To study the following applications of TRIAC : (a) Triac as a static switch (D.C. control). (b) Control of A.C. with A.C. signal. (c) To measure the holding current of IH. Triac.
