CIRCUITO DEL DIODO

UN DIODO conducir corriente continua de manera constante, rectificando la Onda sinusoidal de

corriente continua en una media forma de onda.

RECTIFICADOR CONTROLADO POR SILICON (SCR)

Onda de C.A.

Un Rectificador Controlado por SILICON (SCR or THYRISTOR) es un diodo con una compuerta de

control.

El SCR unicamente se encender cuando la compuerta reciba una seal de los controles del

AVR.

Compuerta

Sin embargo el DIODO, no puede controlar la cantidad de C.D. que entra al campo del excitador, locual es necesaria para controlar el voltage en el Generador.

Apagado

Al incrementarse la Carga aplicada, el tiempo de retardo (T) disminuir automticamente.

OFF OFF

El AVR se estabilizar en un nivel mayor de corriente, cuando el voltage de sensadoretorne a su valor nominal, (previamente ajustado en el Regulador atraves del ajuste delpotenciomentro: VOLTS).

Pulsos al Estator Excitador en Plena Carga X+(F1) XX-(F2)

Mientras mayor es el pulso (rea sombreada en rojo) mayor es la potencia de C.D.suministrada al estator excitador.

Pulsos de C.D. al estator excitador en condiciones desobrecarga X+(F1) XX-(F2)

Los pulsos ahora se consideran de sobrecarga y el AVR requerir de una potencia

adicional para dar una respuesta rpida a los cambios subtos de carga, (reduciendo lacada de voltage).

Esta demanda de repuesta rpida requerir de toda la potencia elctrica disponible poraproximadamente unos 0.3 segundos, hasta que el voltage de salida se ha estabilizado yregresa a su valor nominal.

Corriente alterna Rectificada en C.D. (OndaCompleta, 3 diodos) La potencia de C.A. es rectificada con 4 diodos. Esto permite que el (Tiristor o SCR) se apague enlos espacios entre los pulsos de potencia elctrica.

Pulsos de C.D. sin carga suministrados al Estator Excitador.

Pulsos por segundo = frecuencia del PMG (para un generadorde 8 Polos):- 100 pulsos para 1500 RPM 120 pulsos para 1800 RPM

Pulsos de C.D. a plena carga suministrados al Estator Excitador.

Al incrementarse la Carga aplicada, el tiempo de retardo (T) disminuir automticamente.

Mientras mayor es el pulso (rea sombreada en rojo) mayor es la potencia de C.D.suministrada al estator excitador. El AVR se estabilizara en un nivel mayor de corriente, cuando el voltage de sensadoretorne a su valor nominal, (previamente ajustado en el Regulador atraves del ajuste delpotenciomentro: VOLTS).

t = 20 mSec

La potencia de C.D. al estator excitador es incrementada por la modulacion de ancho de pulsos,manteniendo un voltaje constante. Transitorios / y Sobrecargas son requeridos para condiciones de sobre carga de corta duracion, ypara desempeo en Corto Circuito.
