Abstract

Vienna rectifiers are unidirectional three-level boost rectifiers used in extensive industrial applications. Much effort has been devoted to study the control strategies for Vienna rectifier. This paper introduces the manipulation principles and operation steps of model predictive control strategy based on optimal switching sequence principle. In order to address several issues of the conventional methods, an improved model predictive control strategy has been proposed to regulate the ac currents and neutral point voltage deviation. The proposed strategy has been validated by experiments. The consequences show that the proposed strategy can achieve accurate prediction especially during neutral point voltage unbalance by dealing with constraints and provide excellent performance in dynamic property and stability.
