Aquí tienes la sugerencia completa de cambios para el esquema en Flux. Cuando revises la siguiente lista, utiliza la opción "Apply changes" para incorporarlos al diseño:

Cambios sugeridos en el esquema:

Transformador de 18VAC con toma central:
- Agrega un componente de transformador con secundario de 18VAC y toma central.
- Conecta la toma central a Ground.
Rectificación:
- Agrega 2 diodos 1N4007.
  - Conecta un extremo del secundario del transformador al ánodo del primer diodo, y su cátodo se conectará al nodo +DC.
  - Conecta el otro extremo del secundario al ánodo del segundo diodo, y su cátodo se conectará al nodo -DC.
- La toma central del transformador se usa como referencia para lograr la rectificación de onda completa.
Filtrado:
- Agrega un condensador electrolítico 2200 µF (asegúrate de que su tensión nominal sea adecuada, por ejemplo, 35V o mayor).
  - Conéctalo entre el nodo +DC y [Ground].
  - Agrega otro condensador similar entre el nodo -DC y [Ground] si se desea filtrar ambos railes.
Regulación:
- Agrega el regulador 7812 para generar +12V:
  - Conecta su entrada a la tensión filtrada del nodo +DC.
  - Coloca un condensador de 0.33 µF en la entrada del 7812 y otro de 0.1 µF en su salida.
- Agrega el regulador 7912 para generar -12V:
  - Conecta su entrada a la tensión filtrada del nodo -DC.
  - Coloca un condensador de 0.33 µF en la entrada del 7912 y otro de 0.1 µF en su salida.
Conexiones de Tierra:
- Conecta la toma central del transformador, ambos condensadores de filtrado y los condensadores de desacoplamiento de los reguladores a Ground.

Con estos pasos se obtiene la siguiente configuración:

Table

Bloque	Componente	Función / Conexión
Transformación	Transformador 18VAC con toma central	El secundario proporciona ±18VAC. La toma central se conecta a [Ground].
Rectificación	2× 1N4007	Un diodo de cada extremo del secundario a los nodos +DC y -DC respectivamente, usando la toma central como referencia.
Filtrado	Condensador 2200 µF	Conectado entre +DC y [Ground] (y opcionalmente entre -DC y [Ground]) para suavizar la tensión rectificada.
Regulación	7812 y 7912	7812 recibe +DC y entrega +12V; 7912 recibe -DC y entrega -12V. Cada uno con condensadores de desacoplamiento en entrada (0.33 µF) y salida (0.1 µF).
GND	Ground	Se utiliza como referencia común para la toma central, filtrado y reguladores.
