Abstract

Un convertidor directo (4) presenta una cantidad de primeros grupos de convertidores (6), los que a su vez presentan en cada caso una cantidad de primeros convertidores de corriente (7) conmutados a la red. Los primeros convertidores de corriente (7) están configurados en cada caso al menos como grupos B6 bipolares y están unidos con un primer grupo de arrollamientos (2) de un generador de corriente trifásica (1). La cantidad de primeros convertidores de corriente (7) por primer grupo de convertidores (6) se corresponde con la cantidad de fases del primer grupo de arrollamientos (2). Los primeros convertidores de corriente (7) de al menos uno de los primeros grupos de convertidores (6) presentan un primer punto neutro común (8). El convertidor directo (4) presenta un dispositivo de control (10) común que controla al primer grupo de convertidores (6). El dispositivo de control (10) recibe una modulación nominal (S*) y calcula en base a la modulación nominal (S*) para los primeros convertidores de corriente (7) primeras señales de conmutación (K1). El dispositivo de control (10) calcula al menos para algunas modulaciones nominales (S*) en base al criterio de optimización (OK) en forma estática o dinámica una primera componente de tensión cero (N1), la que es considerada en el calculo de las primeras señales de conmutación (K1). Las primeras señales de conmutación (K1) son transmitidas por el dispositivo de control (10) a los primeros convertidores de corriente (7).
