Sliding mode control of a unity power factor 3-phase AC/DC boost converter
A problem of power factor correction for a class of 3- phase boost AC/DC power converters is addressed in the 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 close to unity (greater than 97%) value of power factor. Sliding mode observers are employed to estimate variation in load and phase resistances - subject of realtime adjustment in the control law. Multi-rate numerical simulation illustrates the efficiency of the proposed methodology and proves its ability to be implemented in digital form.
