i think i know this answer...line commutation is the commutation in single phase inverters/converters when there is current flow back to the source..

It can also refer to a method of turning of a semiconductor device known as a Thyristor or SCR, sometimes called natural commutation. In this method the current between the anode and cathode is interrupted or dropped to a point where the Thyristor can no longer maintain its latch or keep conducting, shutting the device off.

What is a line commutation?

it is the natural commutation making open circuit or short circuit on the thyristor to make it turn off.

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.

What are the types of commutation?

Two types of commutation process 1) Natural commutation 2) Forced commutation
