Abstract

EL CIRCUITO COMPRENDE UN ABASTECEDOR DE VOLTAJE (B) Y UNA FASE DE SALIDA (HB) CON UNA CONFIGURACION PUENTE-H EN EL BRAZO CENTRAL DONDE SE SITUA LA LAMPARA (L).ENTRE LA FUENTE DE VOLTAJE Y LA FASE DE SALIDA SE INTERPONE UNA FASE INTERMEDIA QUE INCLUYE UN CONVERTIDOR (INV) CON UN TRANSFORMADOR (T).LA BOBINA SECUNDARIA DEL TRANSFORMADOR SE DESACOPLA DE UN CONDUCTO DE TIERRA (GND) Y SE CONECTA A UN CIRCUITO RECTIFICADOR DE SALIDA (D2,D3).LA FASE DE SALIDA SE CONECTA A LA SALIDA DEL CIRCUITO DE RECTIFICACION .LA LAMPARA TIENE UNA TERMINAL CONECTADA AL CONDUCTO DE TIERRA, QUE CONSECUENTEMENTE LA BENEFICIA DESDE UN PUNTO VISTA DE SEGURIDAD PUESTO QUE EVITA LA DES-IONIZACION DE LA LAMPARA.
