Abstract

La presente invencion se refiere a un generador ultrasonico de alta potencia (por ej.> 500 W) para utilizarlo especialmente para suministrar potencia ultrasonica, de alta potencia a una carga variable que incluye fluidos comprimibles. El generador incluye un generador de forma de ondas triangular de frecuencia variable acoplado con el modulador de amplitud de impulsos. La salida del modulador de amplitud de impulsos se acopla a las puertas de un transistor bipolar de puerta aislada (IGBT), que amplifica la senal y la entrega a una bobina que se usa para excitar un transductor magnetoestrictivo. En una realizacion, la alta tension de 0-600VDC se entrega a través del colector y emisor del IGBT una vez entregada la senal. La salida del IGBT es una forma de onda cuadrada con una tension de +/- 600V. Esta tension se envía a una bobina enrollada alrededor del transductor ultrasonico. La tension crea un campo magnético sobre el transductor y las propiedades magnetoestrictivas del transductor hacen que el transductor vibre como resultado del campo magnético. El uso del IGBT como dispositivo amplificador obvia la necesidad de un circuito Rectificador Controlado por Silicio (SCR) que se utiliza típicamente en transductores ultrasonicos de baja potencia y que se sobrecalentarían y fallarían en tal aplicacion de alta potencia y de carga variable.
