Inverter of energy storage system

The present invention relates to a bi-directional inverter of the renewable energy storage system which can reduce the switching losses. In one example, provide power to the DC link in the power system, or in the power of the power system to the two-way inverters of the renewable energy storage system to provide to the DC link, the first switch and the connected in series to the DC link switching unit for a second switch connected in parallel to the DC link; An inductor electrically connected to the switching unit; Full-bridge switching unit electrically connected to the inductor; And it discloses a two-way inverter of the renewable energy storage system including the switching portion and the inductor, and a full-bridge control unit electrically connected to the switching unit.
