A Review of Non-Isolated Bidirectional DC-DC Converters for Hybrid Energy Storage System

In recent years, both AC and DC microgrids have attracted a lot of interest in industrial applications. Several sources of renewable energy (such as solar and wind), devices for energy storage, and electronic-based DC loads are all DC. As a result, DC microgrids are preferred over their AC equivalents in some cases to prevent unnecessary DC-AC-DC conversion stages. Researchers use a variety of power-electronic devices to overcome these difficulties. One of them is DC-DC converters. They are particularly useful for regulating the DC voltage and increasing the efficiency of RESs. Bidirectional DC-DC converters are gaining popularity in systems for renewable energy as a way to connect the battery to the energy supply and load. Isolated DC-DC converters and non-isolated DC-DC converters are the two categories of bidirectional DC-DC converters. A review of non-isolated bidirectional DC-DC converter configuration has been demonstrated in this research in recent years. Also, the paper presents a comparison between these topologies and their characteristics.
