A Review on Multi-Port Bidirectional Isolated and Non-Isolated DC-DC Converters for Renewable Applications

To provide a sustainable energy infrastructure, the need for renewable energy development is necessary and we need to develop a multi-port bidirectional DC-DC converter topologies to control the power flow among the modules such as photo voltaic (PV), batteries, energy storage systems (ESS), load, and grid. This paper discusses the various bidirectional isolated and non-isolated DC-DC converter topologies, that are helpful to regulate the power flow in both directions and the high frequency of an isolated transformer between the source and the load. Which leads to many advantages such as safety, flexibility to establish new modules, electromagnetic isolation, high gain, and the ability to transfer large amount of power density. An isolated high-frequency bidirectional dual active bridge power converter is presented to control the power flow in multi-port DC distribution network. Major findings and remarks on the bidirectional isolated and non-isolated DC-DC converters are presented and also the comparison of bidirectional DC-DC converters is presented.
