Abstract

CIRCUITO PARA CONTROLAR EL FACTOR DE POTENCIA EN MOTORES ALIMENTADOS POR UN INVERSOR. EN LA LINEA DE CORRIENTE CONTINUA (B.D.C.C.) QUE VA DEL RECTIFICADOR (10) AL INVERSOR (14), SE INTERCALA UNA RESISTENCIA (27), A CUYOS BORNES SE CONECTAN LAS PATAS DE UN AMPLIFICADOR DIFERENCIAL (28) QUE SE SATURA A MAS EN LOS MOMENTOS EN QUE, DEBIDO A LA POTENCIA REACTIVA, CIRCULA LA CORRIENTE DEL INVERSOR (14) AL RECTIFICADOR (10). ESTOS IMPULSOS SE COMPARAN, EN UN AMPLIFICADOR (31), CON UNA TENSION DE REFERENCIA, AJUSTABLE POR UNA RESISTENCIA VARIABLE (33), QUE SIRVE PARA AJUSTAR EL FACTOR DE POTENCIA; LA SEÑAL OBTENIDA SE INTEGRA CON UNA RESISTENCIA (38) Y UN CONDENSADOR (39), OBTENIENDOSE UNA SEÑAL PROPORCIONAL A LA DIFERENCIA ENTRE EL FACTOR DE POTENCIA REAL Y EL DESEADO, SEÑAL QUE ES APLICADA A LOS CIRCUITOS DE CONTROL DEL RECTIFICADOR (10) Y DEL INVERSOR (14).
