Abstract

Perfeccionamientos en planchas eléctricas con conmutador regulador para el servicio simultáneo de dos circuitos de regulación por lo menos, cada uno de los cuales presenta interruptores respectivos de conexión y desconexión que gobiernan el circuito calefactor de corriente alterna y tiene un circuito generador de señal de mando que emite las señales de mando para dichos interruptores, caracterizados en que los interruptores de conexión y desconexión están constituidos por triacs (4,5); que las señales de mando estan formadas por sucesiones (6,7) de impulsos de longitud dependiente fundamentalmente de la duración de la discrepancia de regulación; y que los impulsos de las sucesiones están sincronizados con el paso de anulación de la tensión alterna alimentadora común a los circuitos de corriente alterna calefactores; además de que las sucesiones de los impulsos llegan al triac pertinente pasando por elementos de conexión de compuerta (8,9) regidos en dependencia de la duración de la discrepancia de regulación, a los cuales conducen conductores de señal para el suministro de señales de conexión de compuerta, de longitud temporal dependiente fundamentalmente de la duración de la discrepancia de regulación, y además de que en el curso de estos conductores de señal se hallan dispositivos de parada (15,16) que completan la duración de las señales de conexión de compuerta ajustándola cada vez a la duración de toda una semionda de la corriente alterna de alimentación.
