Answer 2

Answer:

Commutation is the process by which we can turn OFF a thyristor. So the process of switching OFF a thyristor or SCR is known as Commutation. As we know that once a thyristor starts conducting then it continue to conduct till the current flowing through it reduced below the holding current. A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. By reversing the current direction in the rotating windings each half turn, a steady rotating force (torque) is produced. A function of a commutator is to keep the torque on a DC motor from reversing every time the coil moves through the plane perpendicular to the magnetic field, a split-ring device called a commutator is used to reverse the current at that point.
