Abstract

Un estabilizador electronico de factor de alta potencia para operar una lámpara de descarga de gas a alta presion que comprende una funcion de convertidor de elevacion y una funcion de reduccion. La funcion de convertidor de elevacion y la funcion de reduccion tienen componentes comunes. La combinacion de convertidor elavador-reductor reduce el conteo de partes, como se compara al conteo de partes requeridas para los circuitos de elevacion y reduccion separados de la técnica anterior, haciendo que algunos componentes del circuito individual actuen simultáneamente en las funciones de elevacion y reduccion. El forzamiento rígido de la forma de onda de la corriente de entrada ca para seguir la forma de onda de voltaje de entrada ca se modera, para dar la prioridad de rendimiento a la funcion de reduccion para los componentes comunes. Se permite que las corrientes armonicas entren al sistema con moderacion en el retorno para un sistema menos costoso y más confiable que no compromete el control de energía de la lámpara.
