Abstract :
This paper presents multi-input sliding-mode control schemes for unity-power-factor rectifiers based on buck-boost converters. The proposed controllers can effectively improve the tracking performance of the line current and the output voltage regulation. The sliding surfaces are designed by imposing a desired dynamic behavior on the system, which allows us to determine the main parameters in designing the sliding-mode controller. This results in fast controllers which provide both robustness, with regard to external disturbances, and a good dynamic response of the output voltage
