An unidirectional single-phase three-wire rectifier is proposed in this paper. Such a proposed topology is composed of a non-controlled leg, two controlled legs and a capacitor bank. A suitable model and control strategy of the system, including a synchronization method, are proposed as well. The synchronization method, associated with the PWM strategy, imposes the grid currents to have the same phase...
This paper proposes three topologies of multilevel dynamic voltage restorer (DVR) with application in three-phase systems (balanced and unbalanced) to compensate sags/swells. The topologies use three independent dc-links (one per phase) and each converter is mounted with one three-level NPC leg (3L) and one two-level leg (2L), furnishing a five-level (5L) voltage at its output. This proposed topologies...
An unidirectional three-phase to three-phase dc-link converter is proposed, in this paper. It is composed of three unidirectional ac-dc-ac three-leg converters with a shared-leg. The three-leg converter is composed of a non-controlled leg, two controlled legs and a dc-link. A suitable model and control strategy of the systems, including a synchronization method, are proposed. The synchronization method,...
This paper investigates multilevel topologies based on the concept of nested arrangement. Such topologies are called nested multilevel converters since the central point of the legs are connected at the same point, with the external leg involving the internal one. The main contribution of this paper is to furnish a formal presentation of the nested multi-level configuration, including its generalization...
This paper presents single-phase to three-phase dc-link converters with reduced number of controlled switches for usual or reduced rectifier switch currents. Those converters are composed of either six or eight controlled switches. Suitable modeling and control strategy of the system, including a synchronization method, are proposed. The synchronization method, associated with the PWM command, force...
