Abstract :
In this paper, a control strategy of bidirectional converter for energy storage system in photovoltaic hybrid modules is proposed. The bidirectional converter for energy storage system (ESS) with battery is connected with DC link in parallel which is located between current source flyback converters and unfolding bridge. Because output currents which are generated by flyback converters are rectified sinusoidal waveform, suitable control strategy is required for bidirectional converter. In this paper, a theoretical analysis of the proposed control strategy is provided. And, validity is confirmed through simulation results.
