摘要：

A problem of power factor correction for a class of three-phase boost ac/dc power converters is addressed in this paper. A full-bridge hardware topology is studied and used to address the basics of the efficient power conversion with high values of power factor. The sliding mode control drives the output voltage to the desired dc level in the presence of external disturbances and internal parameter uncertainties while providing a value of power factor that is close to unity (greater than 97%). Sliding-mode observers are employed to estimate variation in load and phase resistances-subject of real-time adjustment in the control law. Multirate numerical simulation illustrates the efficiency of the proposed methodology and proves its ability to be implemented in digital form.
