Abstract

Un circuito de deteccion multitension con optoaislador capaz de manejar un amplio espectro de tensiones de entrada que oscilan entre aproximadamente 9 voltios cc y aproximadamente 240 voltios cc incluye una entrada de tension, un optoaislador, un rectificador, un divisor de tension, los transistores primero y segundo, y un conversor de CC a CC. El divisor de tension operativamente acoplado a los transistores primero y segundo es capaz de dividir en partes iguales la tension de entrada a traves de los transistores primero y segundo. El conversor de CC a CC operativamente acoplado a los transistores, el divisor de tension, y el optoaislador es capaz de mantener una corriente de salida desde el rectificador. El uso del conversor de CC a CC, el divisor de tension, y los transistores provee el beneficio de reducir la potencia disipada por todo el circuito.
