Capacitor commutated converters for HVDC transmission system

The operation of HVDC systems using conventional Line Commutated Converters (LCCs) operating with weak AC systems becomes unreliable due to frequent commutation failures which can occur for any small disturbance in the AC networks. The thesis starts with a brief survey of the present state of the a...
