Generally there are two methods of improving Commutation :-
1.Resistance Commutation
2.Emf or Voltage Commutation
The Commutation can also be improve by using interpoles and compensating windings.
Technology make life easier.
Two types of commutation process 1) Natural commutation 2) Forced commutation
it is a type of forced commutation technique of thyristor
the process of turning off of a thyrisror is known as commutation
Voltage commutation: This is possible in ac circuits...The thyristor gets turned off by reverse bias (negative half cycle) voltage applied across it. This is also called line commutation. Current Commutation: This is possible in dc circuits ...This type of commutation makes use of auxiliary circuit which contains inductor,capacitor,diode and even a thyristor(auxiliary). This is called Forced commutation.
phase controlled RECTIFIER circuit used Natural Commutation......
1.resistance commutation 2.e.m.f commutation
it is the natural commutation ...by making open circuit or short circuit on the thyristor to make it turn off.
last pay drawn meaning? what is basic pension is it pension before commutation or after commutation?
The power of commutation is a power only given to the president of the United States and is the power to commute (reduce) the length of a sentence or a fine by a court.
The purpose of commutation is to switch the direction of current flowing through a motor's windings, thereby controlling the motor's rotation. Commutation ensures that the armature's magnetic field is always in the correct alignment with the stator's magnetic field, enabling smooth and continuous motor operation.
