Abstract

EL CIRCUITO CONSTA DE UN CONVERTOR DC/DC (2), Y UN CIRCUITO DE PUENTE EN FORMA DE -H (HB) CONECTADO AL CONVERTOR (2) MEDIANTE UN CAPACITADOR DE FILTRO (C{SUB.F}), Y QUE TIENE DOS TERMINALES DE SALIDA (O1,O2) ENTRE LOS CUALES LA LAMPARA (L) SE ENCUENTRA CONECTADA. EL CIRCUITO DE PUENTE (HB) COMPRENDE CUATRO INTERRUPTORES CONTROLADOS (M1-M4), CADA UNO DE LOS CUALES SE ENCUENTRA COLOCADA ENTRE UNA TERMINAL ED ENTRADA (I1,I2) Y UNA DE SALIDA (O1,O2), Y QUE PUEDEN SER CONDUCIDOS EN PARES ALTERNANTES PARA FORMAR, JUNTO CON LA LAMPARA (L), DOS CURSOS O DIAGONALES DEL PUENTE (HB). UN TRANSFORMADOR DE ENCENDIDO (TT) POSEE UN BOBINADO SECUNDARIO (W2) CONECTADO EN SERIE CON LA LAMPARA (L), ENTRE LAS TERMINALES DE SALIDA (O1,O2) DEL CIRCUITO DE PUENTE (HB). UN CIRCUITO DE ENCENDIDO (IC;H;C;SC) ES CONECTADO AL BOBINADO PRIMARIO DEL TRANSFORMADOR (TT). UNA UNIDAD DE CONTROL (ECU) CONECTADA A LAS ENTRADAS DE CONTROL DE LOS INTERRUPTORES (M1,M4) DELCIRCUITO DE PUENTE (HB), SE ENCUENTRA COLOCADA PARA DIRIGIR LOS INTERRUPTORES (M1,M4) DE TAL MANERA QUE LOS INTERRUPTORES QUE SON CONDUCTORES CUANDO EL FLUJO DE CORRIENTE COMIENZA EN LA LAMPARA (L), PERTENECEN AL CURSO O DIAGONAL DEL CIRCUITO DE PUENTE (HB), PARA EL QUE LAS CORRIENTE QUE FLUYEN EN LA LAMPARA (L) COMO RESULTADO DEL FLUJO DE UNA CORRIENTE IMPULSADA EN EL BOBINADO PRIMARIO DEL TRANSFORMADOR DE ENCENDIDO (TT), Y COMO RESULTADO DE LA DESCARGA DEL CAPACITADOR DE FILTRO (C{SUB.F}), RESPECTIVAMENTE, CIRCULAN EN LA MISMA DIRECCION,
