摘要：
This paper presents three three-phase AC-DC configurations in which two are unidirectional and have reduced switch count. The investigated topologies have one DC-link and are composed by two converters in series connection through transformers, that process part of the total power, while the conventional converters have two DC-links and a transformer processing all the power. The replacement of switches by diodes aims to reduce the system complexity and costs, so that less driver circuitry is necessary. The proposed converters presented equal or less power losses in relation to the conventional ones. The model and control strategy of the systems, as well as simulation and experimental results are presented.
