Abstract:
To date three-phase boost rectifiers, due to their high efficiency, good current quality and low EMI emissions are widely used in industry as Power Factor Correction (PFC) converters. Performance criteria of these converters significantly improve with increasing the switching frequency, and highly depend on the control strategy used. This paper introduces a simple and fast control strategy for three-phase boost rectifiers. The proposed method maintains the advantages of the other schemes, including high efficiency, fast dynamic response, unity power factor, sinusoidal input currents and regulated output voltage. In particular, by the introduction of a modified vector classification algorithm nonlinear function generations, also abc-dq and dq-αβ transformation carried out in conventional SVM-based strategies are avoided. Therefore, there is no need for current regulators in the d-q frame, and associated control difficulties are removed. Simulation results confirm the validity of the analytical work
