摘要：
This paper proposes a new non-isolated low power Multi-port DC/DC converter for PV/Battery/Load systems. The presented circuit consists of primary converters and can extract maximum power from PV and deliver it to the load port, which is a bipolar DC microgrid. In addition, the presented circuit can regulate different bipolar output loads on equal voltage levels. In this converter, excessive energy produced by PV is saved in the battery to support the system when PV energy is insufficient for output load. Although the input to output conversion ratio is regulated to make this system suitable for grid voltage levels, the presented circuit can be used in off-grid systems as well. After theoretical analysis, simulation of this system with MatLab/Simulink proves the performance.
