摘要：
A multiport DC-DC converter for PV applications is proposed in this paper. A proposed converter provides a power electronic interface to integrate PV and energy storage systems to DC micro grid. It has the capability of inter source power sharing. A high voltage gain is achieved at low duty cycle by using a switched capacitor cell. The proposed topology is light weight and less expensive due to usage of a single inductor and less component count. On the basis of possible directions of power flow different operating modes are defined and are analyzed in steady state. A robust control scheme is designed to regulate the output voltage over a wide range of variation in line voltage or in load. The performance of the converter is validated and verified through simulation results.
