Home / Triac Characteristics
Object:
1. To study the gate characteristics of a TRIAC in the following modes :
(a) Mode I+ :Â i.e. T2 positive with respect to T1 and gate positive with respect to TÂ 1
(b) Mode I- :Â i.e. T2 positive with respect to T1 and gate negative with respect to TÂ 1
(c) Mode III+ :Â i.e.T2 negative with respect to T1 and gate positive with respect to TÂ 1
(d) Mode III- :Â i.e. T2 negative with respect to T1 and gate negative with respect to TÂ 1
2. To study the terminal characteristics of a TRIAC in the following modes :
(a) Mode I+ :Â i.e. T2 positive with respect to T1 and gate positive with respect to TÂ 1
(b) Mode III+ :Â i.e. T2 negative with respect to T1 and gate positive with respect to TÂ 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.
