Abstract

Due to the increasing penetration of distributed generation systems, the desire to use DC smart grids has increased. DC smart grids are preferred to AC grids because these networks are more compatible with renewable sources that generate DC electricity. This paper presents the design of a new three-port isolated DC-DC converter for photovoltaic (PV)-battery application in the DC smart grid. In the proposed converter, by combining the required converters for PV and battery, the number of required converters has been reduced so that the function of charging/discharging the battery, as well as tracking the maximum power point of solar panels, can be done with the proposed converter. As a result, the number of required parts and the cost of the system are reduced and the efficiency of the converter increases. Finally, the converter's performance has been evaluated with the help of analysis and simulation, and the obtained results indicate the proper performance of the proposed converter.
