Usually commutating Capacitors are used in bistable multivibrators.
To change the states of two transistors in bistable MVs, a trigger is applied.
But due to the capacitance at base of transistor it takes sometime (delay) to change the state.
To overcome this problem Commutating capacitors are used.
So these are also known as Speed up capacitors or Transpose Capacitors as they speed up the operation.

What are the types of commutation?
Two types of commutation process 1) Natural commutation 2) Forced commutation
How commutation can be improve?
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.
What is load commutation?
it is a type of forced commutation technique of thyristor
What is commutation of thyristor?
the process of turning off of a thyrisror is known as commutation
What is the difference between current and voltage 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.
Natural commutation is used in which kind of circuit?
phase controlled RECTIFIER circuit used Natural Commutation......
What are the problems of commutation in a DC generator?
1.resistance commutation 2.e.m.f commutation
What is a line commutation?
it is the natural commutation ...by making open circuit or short circuit on the thyristor to make it turn off.
Definition of last pay drawn?
last pay drawn meaning? what is basic pension is it pension before commutation or after commutation?
What is the power of 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.
What is purpose of commutation?
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.
