摘要：

This paper proposes three dynamic voltage restorer (DVR) topologies. Such configurations are able to compensate voltage sags/swells in three-phase four-wire (3P4W) systems under balanced and unbalanced conditions. The proposed systems use two independent dc links. Proposed configurations present advantages in terms of switch blocking voltages and consequently lower dc-link voltage rating. The complete control system, including the pulsewidth modulation (PWM) technique, is developed, and comparisons between the proposed configurations and a conventional one are performed. Simulation and experimental results are provided to validate the theoretical approach.
