|GTO and Duality - For a better matching of phase controlled converters and power network|
|Author(s)||P. Ladoux, Y. Chéron; H. Foch|
The thyristor has long been the only controlled component allowing to switch high power (MW). Mostly used in rectifier structures, the thyristor is now challenged by by the GTO that provides blocking capability.
Using the duality and soft commutation concepts, the authors propose "new" topologies for turn-off and turn-on controlled rectifiers, as well as some series and parallel assemblies. The AC- and DC-side performances of these rectifiers are then exposed with the aid of the elementary commutation cell concept. The problems related to the implementation of such turn-off controlled rectifiers are finally discussed.
