Mr Santoshkumar u r terribly wrong.
There r two types of commutation one is Natural commutation
and the other is Forced commutation and load commutation is
a type of natural commutation.
Commutation means to turn-off.
In load commutation the load helps in commutating the device.
Suppose a thyristor is there and if anyhow the thyristor can
be reverse biased by increasing the load side voltage so
that the current falls below the holding current then the
thyristor will turn off or will be commutated.This is called
load commutation.
This type of commutation is used where the applied voltage
to a device never passes through zero (dc voltage). Since
the voltage cycle never passes thro zero the device cannot
be line commutated and so one is bound to use load
commutation as the only means to commutate the device.
