Each multiport converter topology has different number of power processing stages, different number of switches and different control techniques. This paper proposes a single-stage multiport power converter topology for integrating PV-Battery to the three phase ac load application. Power flow between all the three ports are managed using Finite Control Set Model Predictive technique. The proposed converter has reduced number of switches and conversion stages to connect PV and battery to the three phase ac load system compared to conventional switches. The converter topology is based on bidirectional simultaneous power conversion of dc/dc and dc/ac system. The topology allows the connection of a low voltage battery that acts as a buffer in the standalone system. Simulation results show the efficacy of the multiport bidirectional converter to manage the power flow between PV- Battery connected to three-phase ac load system. © 2022 IEEE.Battery Energy Storage SystemsBidirectional power flowDC/AC power convertersDC/DC power convertersFinite Control Set Model Predictive ControlThree-port converter
