Abstract
Perfeccionamientos en dispositivos de control de un montaje trifásico a tiristores, que comprende un transformador monofásico único conectado entre dos fases de una tensión trifásica de sincronización, un medio para engendrar, a partir de la tensión de sincronización, una tensión auxiliar de igual frecuencia y que varia constantemente en el mismo sentido para cada semi-periodo de la tensión de sincronización, un comparador de amplitud que proporciona frentes de ondas rígidos cada vez que la amplitud de la tensión auxiliar es igual a la de una tensión continua de control aplicada al comparador, y medios para convertir cada uno de los frentes de ondas rígidas en seis señales en almenas contíguas, teniendo cada una, una duración de 60º eléctricos, coincidiendo el frente de establecimiento de la primera de esta seis señales con el frente de onda rígido, comprendiendo los medios de conversión un bucle de subordinación de fase que incluye un comparador de fase una de cuyas entradas se conecta ala salida del comparador de amplitud y cuya salida se conecta a la entrada de control de un oscilador de control por tensión, conectándose la salida del oscilador de control por tensión, conectándose la salida del oscilador a la entrada de un contador que trabaja como divisor de frecuencia, cuya salida se conecta a la otra entrada del comparador de fase, caracterizados porque el contador está agenciado para dividir por seis la frecuencia del oscilador y para proporcionar en tres salidas tres informaciones se conteo de peso respectivo, 1, 2 y 4 en el código decimal codificado binario, porque las informaciones de conteo son decodificadas en un decodificador para proporcionarlas seis señales en almenas y porque estas últimas son respectivamente aplicadas a seis interruptores accionados para permitir o bloquear la transmisión, hacia los seis amplificadores de potencia, de señales proporcionadas por un oscilador local y de frecuencia sensiblemente más elevada que la del oscilador del bucle.
