A review of power converter topologies with medium/high frequency transformers for grid interconnection systems

In recent years, power electronics has evolved dramatically due to their importance in power extracted management from renewable sources. In this paper an overview of grid interconnection systems with galvanic isolation is presented. The most common used topologies from AC/AC, AC/DC, DC/AC and AC/AC conversion are analyzed y summarized in order to provide a good understanding of the existing technologies.
