With neat sketch explain four modes of operation of a TRIAC?
With neat sketch explain four modes of operation of a TRIAC?
Last answer:
Modes of operation of a TRIAC: There are four different operating modes of TRIAC: 1) MT2 and gate are positive with respect to terminal MT1(Mode1) : Here terminal MT2 is positive ... junction P2-N2 is forward biased, current carriers are injected and therefore, the TRIAC is turned on.
