Abstract

At the current state, the development of Medium Voltage Solid-State Transformers is mainly limited by the maximum voltage rating supported by the available power devices as well as by the existing circuit topologies. This paper introduces, for the first time, a new conversion structure for three-phase isolated AC/AC converter namely "ROMAtrix converter". The proposed modular architecture permits to halve the power devices voltage ratings for a given grid voltage, so enabling connections to a wider range of MV networks. In this paper, the concept of the ROMAtrix converter, including the detailed description on allowed switching configurations and the dedicated modulation strategy, have been presented. Simulation results, achieved in PLECS environment, are show and discussed in order to highlight the features of the structure.
