Abstract

Un dispositivo de control de carga para controlar la energía entregada desde una fuente de alimentación de CA a una carga eléctrica puede tener un circuito de activación de compuerta de lazo cerrado para controlar un conmutador semiconductor de un dispositivo conductor controlable. El dispositivo conductor controlable se puede acoplar en serie entre la fuente y la carga. El circuito de activación de compuerta puede generar una señal objetivo en respuesta a un circuito de control. El circuito de activación de compuerta puede conformar la señal objetivo durante un período de tiempo y puede aumentar la señal objetivo a un nivel predeterminado después del período de tiempo. El circuito de activación de compuerta puede recibir una señal de retroalimentación que indica una magnitud de una corriente de carga conducida a través del conmutador semiconductor. El circuito de activación de compuerta puede generar una señal de control de compuerta en respuesta a la señal objetivo y la señal de retroalimentación, y convertir el conmutador semiconductor en conductor y no conductor en respuesta a la señal de control de compuerta.
