In this paper a new topology, isolated Buck/Boost bidirectional DC-AC three phase, for interconnecting a DC micro grid with conventional three-phase AC network, is presented. Its operating principle is explained, and a switching strategy is presented to reduce total harmonic distortion and operate the devices with minimal switching losses. Finally the simulation results are shown to evaluate the performance of the converter.
