A New Phasorial Oriented Single PI Loop Control for Industrial VSC-PFC Rectifiers Operating Under Unbalanced Conditions

Due to several reasons, the three-phase voltages of power grids cannot be balanced. The performance of AC-DC converters using dq0-based controls can be severely affected by the presence of unbalanced input AC voltages. Different to these proposals, this study presents a new easy-to-implement control scheme based on a single PI loop algorithm for VSC-PFC rectifiers using a phasorial approach. This ...
