In which type of commutation does the current naturally fall to zero due to the alternating supply? (A) Forced commutation (B) Resonant commutation (C) Natural commutation (D)...
Define Commutation and state the methods of commutation. Commutation is the process of turning off a conducting thyristor. There are two methods for commutation viz. natural...
Define forced commutation. In case of DC circuits, there is no natural current zero to turn OFF the SCR. In such circuits, forward current must be forced to zero with an external...
