“…Microgrids can operate either isolated or interconnected with the electric power system (EPS), at low or medium voltage, by means of bidirectional DC–AC power electronic interfaces that control the power flow from and to the microgrid [10]. When this interconnection requires galvanic isolation, for security purposes and to facilitate the adaptation to different voltage levels, transformers become necessary.…”

In this study, a new isolated bidirectional DC-to-three-phase AC converter for integration of renewable energy sources to the electric grid is presented. The main features of this topology are galvanic isolation, capability to control the power flow bidirectionally, soft switching, unit power factor under open-loop control and also allow step up and step down the voltage. Its operation principle is described and a modulation strategy is proposed, which allows to control the power flow according to the requirements of the load and to operate with minimum switching losses owing to the soft switching. The results revealed the feasibility of the proposal with a THD i of the AC current waveforms below 5% and the power factor above 0.98.
