Abstract

Una resistencia intersificadora de luz para utilizarse con un reductor de luz con control de fase, y particularmente un reductor de luz triac, incluye un filtro EMI seleccionado con una impedancia alta para evitar un voltaje excesivo y corrientes pico en el filtro debido a resonancia con la forma de onda AC con control de fase en ángulos de conduccion bajos, cuando la carga presentada por la lámpara es baja. La resistencia también incluye un convertidor DC-DC del tipo de modalidad con interruptor que mantiene el filtro EMI cargado y evita la activacion equivocada del reductor de luz triac y por lo tanto el parpado de una lámpara operada con la resistencia de intensificacion de luz.
