Which among the following is the most dominant converter employed in FACTS Controllers? Correct Answer Voltage-sourced converters
Practically speaking, the most dominant converters that are employed in FACTS Controllers are the voltage sourced ones. Their operations are based on thyristors with gate turn-off capability where the power reversal exhibits reversal of current keeping unidirectional-voltage. On the other hand current-sourced converters having thyristors with no gate turn-off capability are more economical for large HVDC schemes. In them the reversal of power flow can be achieved with reversal of voltage only keeping unidirectional current.
