Abstract

UN CIRCUITO PARA ACCIONAR REGULARMENTE LAMPARAS FLUORESCENTES (102,104,106) DESDE UNA TENSION DE ALIMENTACION DC, INCLUYE: NODOS DE ENTRADA (174,176) QUE TIENEN CONDENSADORES DE ENTRADA (184,186) CONECTADOS ENTRE ELLOS; UN INVERSOR TRANSISTOR DE MEDIO PUENTE (178,180) CONECTADO ENTRE LOS TERMINALES DE ENTRADA; UN OSCILADOR RESONANTE LC (196,198) ACOPLADO EN SERIE ENTRE LOS TRANSISTORES DE MEDIO PUENTE Y LOS CONDENSADORES DE ENTRADA, UN TRANSFORMADOR DE SALIDA (212) QUE TIENE UN BOBINADO PRIMARIO (214) CONECTADO EN SERIE CON EL INDUCTOR LC (196) Y EN PARALELO CON EL CONDENSADOR LC (198), Y UN BOBINADO SECUNDARIO (216) PARA LA CONEXION DE CARGA DE LA LAMPARA; Y DOS DIODOS DE BLOQUEO DE VOLTAJE, PRIMARIO Y SECUNDARIO (215A,215B) CONECTADOS ENTRE UN PUNTO INTERMEDIO DEL BOBINADO PRIMARIO Y LOS RESPECTIVOS NODOS DE SALIDA. LOS DIODOS DE BLOQUE DE VOLTAJE, EN CONJUNCION CON LOS CONDENSADORES DE ENTRADA, PROPORCIONAN UN INCREMENTO SIGNIFICATIVO EN LA REDUCCION DE LA ENERGIA TRANSFERIDA A LAS LAMPARAS CUANDO EL SUMINISTRO DE VOLTAJE DC SE REDUCE, CONSIGUIENDO QUE LA REGULACION DE LA LAMPARA SE EFECTUE SIMPLE Y EFICIENTEMENTE POR REDUCCION DEL VOLTAJE DC SUMINISTRADO.
