Abstract

Un circuito del reactor que utiliza un optoacoplador (140) para proporcionar aislamiento eléctrico del control de atenuacion (152) del resto del reactor. El optoacoplador (140) se opera en el rango lineal para proporcionar atenuacion continua de las lámparas. El circuito utiliza además una combinacion de diodos y un puente de diodo (206) para guiar la corriente desde el sensor de corriente durante las condiciones de lámpara apagada de tal manera que el inversor (100) mantendrá la operacion a una frecuencia baja, con lo cual el voltaje de salida se maximiza. Un devanado de pinza se utiliza para asegurar que el voltaje no exceda el voltaje de vía de CD.
