Abstract
CONVERTIDOR PARA LA ALIMENTACION DE UNA LAMPARA DE DESCARGA (1) DE FARO DE VEHICULO AUTOMOVIL QUE LLEVA UN CIRCUITO PRIMARIO (11, Q1) Y UN CIRCUITO SECUNDARIO (12A, D2; 12B, D3) QUE LLEVA DOS BRAZOS (12A, 12B) MONTADOS EN PARALELO QUE ESTAN CADA UNO ACOPLADOS POR INDUCCION MUTUA CON EL CIRCUITO PRIMARIO (11) Y DOS DIODOS (D2, D3) MONTADOS DE MANERA QUE EVITE QUE UNO DE LOS BRAZOS NO SE DESCARGA EN EL OTRO, SIENDO LA RELACION DE TRANSFORMACION, POR INDUCCION MUTUA CON EL CIRCUITO PRIMARIO (11) DE UNO (12B) DE LOS DOS BRAZOS SUPERIOR A LA RELACION DE TRANSFORMACION DEL OTRO (12A), LLEVANDO EL BRAZO (12B) DE RELACION DE TRANSFORMACION MAS ELEVADA UN INTERRUPTOR (Q2) QUE ES CONTROLADO POR UN DISPOSITIVO ELECTRONICO DE CONTROL (7), DE MANERA QUE ESTE CERRADO MIENTRAS LA TENSION DE LA LAMPARA SEA SUPERIOR A UNA TENSION DE UMBRAL DADA Y A ESTAR ABIERTO CUANDO ESTA TENSION ES INFERIOR A ESTE UMBRAL.
