Abstract

SE PRESENTA UN APARATO Y METODOS PARA LA REGULACION DE ENERGIA DE CORRIENTE ALTERNA PRIMARIAMENTE DISEÑADOS PARA CARGAS INDUCTIVAS (POR EJEMPLO LUCES FLUORESCENTES, MOTORES, ETC) QUE SUMINISTRA UNA SUBSTANCIAL REDUCCION EN EL CONSUMO DE ENERGIA MIENTRAS QUE TAMBIEN SUMINISTRA UN FACTOR DE POTENCIA DE CARGA, UNA DISTORSION ARMONICA REDUCIDA, UN FACTOR DE CRESTA REDUCIDO Y RUIDO REDUCIDO. EL SISTEMA ES AUTOAJUSTABLE PARA UNA AMPLIA BANDA DE CARGAS Y PUEDE REDUCIR EL CONSUMO DE ENERGIA EN UN 25% EN CARGAS DE ILUMINACION MIENTRAS QUE PRODUCE UNA REDUCCION MINIMA EN LA SALIDA DE LUZ. EL SISTEMA UTILIZA UN TRIAC (32) Y UN BANCO DE CONDENSADORES EN PARALELO (58) EN SERIE CON LA CARGA (22). EL TRIAC (32) SE ENCIENDE EN RESPUESTA A UNA TENSION DIFERENCIAL CERCANA AL CERO MEDIDA A TRAVES DEL TRIAC (32) Y SE APAGA CERCA DEL PICO DE CADA MEDIO CICLO DE CORRIENTE ALTERNA DERIVANDO LA CORRIENTE ALREDEDOR DEL TRIAC (32). EL CONDENSADOR (60) ABSORBE EL PICO DE TENSION INDUCTIVA DE APAGADO CAUSADO POR EL CAMPO MAGNETICO COLAPSANTE EN LA REACTANCIA EN EL INSTANTE DEL APAGADO DEL TRIAC. ESTA ENERGIA, A SU VEZ, SUMINISTRA UN PERIODO DE ENCENDIDO MAS LARGO PARA LA LAMPARA, PERMITIENDO DE ESTA FORMA MAS LUZ Y UNA EFICIENCIA DE FUNCIONAMIENTO INCREMENTADA. EL MOMENTO DE APAGADO SE AJUSTA PARA REGULAR LA ENERGIA A UN NIVEL REDUCIDO SENSIBLE A LA TENSION DE LA LINEA, LA CORRIENTE DE CARGA Y LAS SEÑALES DE DETECCION DE LA POTENCIA DE CARGA.
