Abstract

SE TRATA DE UN APARATO DE VISION DE TUBO DE IMAGEN, CONCRETAMENTE DE UN RECEPTOR DE TELEVISION O DE UN MONITOR, QUE SE CARACTERIZA MEDIANTE UNA ENTRADA DE CORRIENTE SINOIDAL DE LA RED. ESTO SE CONSIGUE SIN NECESIDAD DE LA ETAPA DE POTENCIA ADICIONAL QUE ANTES SE ENCONTRABA EN LOS APARATOS DE VISION DE TUBO DE IMAGEN CONOCIDOS, QUE TIENEN UNA PARTE DE LA RED DE CONEXION CONECTADA AL RECTIFICADOR DE PUENTE DE LA RED. ESTO SE CONSIGUE AL COLOCAR LA PARTE DE LA RED DE CONEXION DE FORMA CONOCIDA COMO UN FILTRADOR DE LA ONDA SUPERIOR 2 Y ACTIVO CON LA SEPARACION DE LA RED Y LA ETAPA FINAL HORIZONTAL 8 CONECTADA DIRECTAMENTE A LA RED A MODO DE ETAPA HORIZONTAL 8 FINAL QUE SE REGULA AUTOMATICAMENTE. LA ETAPA FINAL HORIZONTAL 8 SE TIENDE DE TAL FORMA QUE NO PUEDE REGULAR COMPLETAMENTE LA TENSION DE ALIMENTACION DEL FILTRO DE ONDA SUPERIOR 2. LA ALIMENTACION DE CORRIENTE CONTINUA NO SE DESVIA POR LAS PARTES DE CONEXION 3, 6, 7 DIRECTAMENTE DE LA SALIDA DEL FILTRO DE ONDA SUPERIOR 2. LA ALIMENTACION DE CORRIENTE CONTINUA DE LAS PARTES DE CONEXION SENSIBLES DEL APARATO SE DESVIA POR SU LADO LATERAL DE LA ETAPA FINAL HORIZONTAL 8.
