Line Commuted:
A line commutated converter is an electrical converter in which the output voltage is controlled by the relative positions of the input and output conductors. This type of converter employs a commutating circuit, typically a thyristor or a gate-turn-off thyristor ( GTO thyristor), to switch the input current between the primary and secondary windings.
Explanation:
In a line commutated converter, the primary winding is connected to the input voltage and the secondary winding is connected to the load.
The thyristor acts as a controllable switch that can be triggered to turn the primary and secondary windings on and off.
The thyristor is connected between the control circuit and the primary winding.
The control circuit sends a pulse or a reference voltage to the thyristor, controlling its conduction.
As the thyristor conducts, it allows current to flow from the primary to the secondary winding.
This allows the output voltage to be controlled according to the changes in the input voltage.
The thyristor is typically triggered using a pulse signal from the control circuit.
By controlling the thyristor, the output voltage can be made to vary according to the input voltage.
Line commutated converters are commonly used in power electronics systems, such as battery-powered systems, renewable energy systems, and industrial control applications
