Abstract In this paper, a control method of bidirectional converter for photovoltaic parallel DC-Module energy storage system(ESS) is proposed. The proposed bidirectional converter is connected in parallel with DC link which is located between current source flyback converters and unfolding bridge. Because output current of converters are rectified sinusoidal waveform, bidirectional converter requires suitable control method. Therefore, a theoretical analysis of the proposed control method is provided. Also, the validity of the proposed one is confirmed through experiment results.
