Abstract

EL INVENTO SE REFIERE A UNA FUENTE DE ALIMENTACION DE ALTA FRECUENCIA PARA LA ALIMENTACION CON CORRIENTE CONTINUA DE UNA ESTACION DE SOLDADURA (W) MEDIANTE UN ESTRANGULADOR (80) UTILIZANDO UN INVERSOR DE ALTA FRECUENCIA (10) CON UN TRANSFORMADOR (20) QUE CONSISTE DE UN TRANSFORMADOR DE NUCLEO CUYO BOBINADO SEGUNDARIO (40) TIENE SEGMENTOS DE BOBINADO ENSERIE (42, 44) QUE FORMAN CON SU NUDO (50) CONJUNTO UNA DE LAS SALIDAS DE LA FUENTE DE ALIMENTACION Y CON SUS OTROS EXTREMOS DE BOBINADO (52, 54) ESTAN CONECTADOS CON LA OTRA SALIDA (56) UTILIZANDO DISPOSITIVOS DE CORRIENTE DE VIA UNICA (60, 62). EL NUCLEO DEL TRANSFORMADOR SE MAGNETIZA Y REMAGNETIZA ALTERNANDO POR EL BOBINADO PRIMARIO (22, 24), INDUCIENDO EN LOS SEGMENTOS DE BOBINADO SEGUNDARIO (42, 44) IMPULSOS DE CORRIENTE. EL INVENTO PREVE UNA MODIFICACION DE LA SALIDA DEL TRANSFORMADOR (20). EN ELLO, SEGUN EL INVENTO, SE ASIGNA A CADA SEGMENTO DEL BOBINADO (42, 44) DEL BOBINADO SEGUNDARIO (44) UN BOBINADO DE AYUDA O ADICIONAL (200, 202) CON EL FIN DE PRODUCIR UN IMPULSO ADICIONAL DE CORRIENTE AL MAGNETIZAR O REMAGNETIZAR EL NUCLEO (10), ADEMAS UN DISPOSITIVO PARA LIMITARA EL IMPULSO ADICIONAL DE CORRIENTE Y PARA SUMAR EL IMPULSO ADICIONAL DE CORRIENTE LIMITADO AL IMPULSO DE CORRIENTE DEL SEGMENTO DE BOBINADO ASIGNADO (42, 44) DEL BOBINADO SEGUNDARIO. A RAZON DE SOLAPAR LOS IMPULSOS ADICIONALES DE CORRIENTE A LOS DE LOS SEGMENTOS DE BOBINADO DEL INVERSOR LLEVA A UNA TENSION DE SALIDA MAXIMA DE LA FUENTE DE ALIMENTACION DE CORRIENTE CONTINUA QUE ES SUSTANCIALMENTE MAYOR QUE LA TENSION DE SALIDA MAXIMA DE LAS FUENTES DE ALTA FRECUENCIA CORRIENTES, PUDIENDO OBTENER CORRIENTES DE SALIDA MAS ALTAS SIN TENER QUE AUMENTAR LA CORRIENTE PRIMARIA.
