Abstract

Un filtro (28) de linea de entrada separa una fuente (22) de energia sinusoidal de una etapa (26) de conmutacion de energia que tiene una seccion (44) de conmutacion en serie y una seccion (46) de conmutacion de mordaza. Tanto la seccion (44) de conmutacion en serie como la seccion (46) de conmutacion de mordaza incluyen pares (68-70 y 86-88) complementarios de MOSFET de alta energia y alta velocidad. La seccion (44) de conmutacion en serie se conecta en serie entre el filtro (28) de linea de entrada y el inductor (42) de un filtro (38) de carga de salida entre la etapa (26) de conmutacion de energia y una carga (24). La seccion (46) de conmutacion de mordaza se conecta para derivar el inductor (42) y la carga (24). La operacion sincronica se logra al operar alternativamente las secciones de conmutacion en serie (44) y de mordaza (46) en las condiciones conductivas en una frecuencia de modulacion de anchos de impulsos elevada. El ciclo de trabajo se selecciona para proporcionar una forma de onda de salida sinusoidal con una amplitud deseada. Un controlador (56) programable basado en microprocesador proporciona las senales (102, 106) de control para la conduccion alternativa de la seccion de conmutacion en serie (44) y de mordaza (46). Un intervalo (110, 112) de tiempo muerto almacenado en la memoria en el controlador (56) separa las senales (102, 106) de control para una operacion confiable y eficiente. El intervalo (110, 112) de tiempo muerto puede ser constante, o puede variarse de acuerdo con la variaciones de energia de carga.
