Abstract
Un dispositivo de control de carga (por ejemplo, un accionador LED) para controlar la intensidad de una carga de iluminación (por ejemplo, una fuente de luz LED) puede proporcionar un rango de salida amplio y ajuste libre de parpadeo de la intensidad de la carga de iluminación. El dispositivo de control de carga puede comprender un circuito de regulación de carga, un circuito de control, y un circuito de filtro (por ejemplo, un circuito de filtro de vagón de carga) que opera en una manera diferente dependiendo de una corriente objetivo. Cuando la intensidad de la carga de iluminación está cerca de una intensidad de extremo bajo, el circuito de control puede ajustar una frecuencia operativa del circuito de regulación de carga en respuesta a la corriente objetivo, y puede controlar el circuito de filtro para filtrar una señal de retroalimentación de corriente durante una ventana de filtro que se repite sobre una base periódica. Cuando la intensidad de la carga de iluminación está cerca de una intensidad de extremo alto, el circuito de control puede controlar el circuito de filtro para filtrar constantemente la señal de retroalimentación de corriente.
