Abstract

In this paper, a switching 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(CSFC) and unfolding bridge. Because CSFC generates rectified sinusoidal current, the bidirectional converter requires suitable control strategy. Therefore, a theoretical analysis of the proposed switching control strategy is presented. And, validity is confirmed through simulation results.
