Abstract

INVERSOR DE TRANSISTORES PARA ENCENDIDO DE UNA LAMPARA FLUORESCENTE. CONSTA DE DOS TRANSISTORES (1, 2) Y UN CIRCUITO RESONANTE EN SERIE, CARACTERIZADO PORQUE LOS TRANSISTORES, CONECTADOS EN SERIE A TRAVES DE LA FUENTE DE CORRIENTE CONTINUA (12), ACCIONAN UNA CARGA (7) CONECTADA EN PARALELO CON LOS CONDENSADORES DEL CIRCUITO RESONANTE EN SERIE; PORQUE SE CONSIGUE UN ENCENDIDO INSTANTANEO EN EL MOMENTO DE CONECTAR EL CONMUTADOR; PORQUE EL FACTOR DE POTENCIA AUMENTA, REDUCIENDOSE LAS PERDIDAS DE POTENCIA REACTIVA; PORQUE UTILIZA LA ELEVADA TENSION INDUCIDA EN LOS CONDENSADORES PARA ENCENDER LAS LAMPARAS FLUORESCENTES, CONMUTANDO ALTERNATIVAMENTE LOS TRANSISTORES (12) EN SINCRONIZACION CON LA FRECUENCIA NATURAL DEL CIRCUITO RESONANTE.
