Control digital de convertidores AC/DC bidireccionales sin sensor de corriente de dos niveles con alto factor de potencia

Control digital de convertidores AC/DC bidireccionales sin sensor de corriente de dos niveles con alto factor de potencia

Abstract

En corrección de factor de potencia monofásico es necesario medir tres variables: la tensión de red, la corriente demandada por la carga de la red y la tensión DC en lado de continua del convertidor. Sin embargo, en ciertas topologías es posible evitar la medida de alguna de ellas, reduciendo así el número de variables a medir y el coste asociado al sensado y acondicionamiento de éstas para su posterior tratamiento. Este aspecto es el que se plantea en el trabajo que aquí se presenta. La idea es no realizar la medida de la intensidad de entrada (i g). En su lugar, la corriente de entrada es “reconstruida” digitalmente basándose en la emulación de la etapa de corrección de factor de potencia en un dispositivo FPGA. La topología sobre la que se aplica la propuesta es el convertidor puente completo, operando como rectificador y como inversor.
