TRIAC MCQ [Free PDF] - Objective Question Answer for TRIAC

WebIf voltage exists for a period of the rated turn off time of the device, then the negative polarity of the voltage across the outgoing thyristor will turn it off. Class F Type. Here, the duration of the half-cycle must be greater than the turn-off time of the thyristor. This commutation process is similar to the concept of a three-phase converter. http://m.manuals.plus/m/8e9e8a2c42da7181178fd8b3b584d61dc371d5f7bbcc9767138f79f2bfddae70.pdf
