Abstract

SE PROPORCIONA UN SISTEMA DE CONTROL DE UNA CELULA OPTICA (UNA VALVULA LUMINOSA) QUE COMPRENDE UN PRIMER CIRCUITO (OSCILADOR) ALIMENTADO POR UNA FUENTE DE ENERGIA DE BAJO VOLTAJE E INCLUYE UN BOBINADO PRIMARIO DE LA BOBINA DE INDUCCION Y UN CIRCUITO (RESONANTE) SECUNDARIO QUE INCLUYE LA CELULA OPTICA Y UN BOBINADO SECUNDARIO DE LA BOBINA DE INDUCCION. EL CIRCUITO SECUNDARIO INCLUYE LA INDUCTANCIA DE UN BOBINADO SECUNDARIO Y LA CELULA OPTICA, Y LA BOBINA DE INDUCCION PROPORCIONA UN ACOPLAMIENTO DEBIL ENTRE LOS BOBINADOS PRIMARIOS Y SECUNDARIOS. EL CIRCUITO RESONANTE PROPORCIONA UN COEFICIENTE DE SOBRETENSION ELEVADO Y UNA ESTABILIDAD EXTRAORDINARIA Y LA CONFIGURACION QUE PROPORCIONA LA INVENCION FACILITA UNA REDUCCION SIGNIFICATIVA EN EL TAMAÑO DEL SISTEMA DE CONTROL.
