Abstract: | DC micro-grid is a grid form integrating distributed energy systems with utility power systems. As the indispensable interface circuits, bidirectional DC-DC converters (BDC) play an important role in DC micro-grids. It can effectively improve the distributed energy utilization ratio as well as the performance and quality of DC micro-grids. After the brief introduction of DC micro-grid system architectures, the four typical applications of BDC in DC micro-grids are classified and aggregated. This paper concludes the current research achievements, and focuses on the applications of BDC in DC micro-grids. Finally, the future development tends of BDC are discussed on the view of DC micro-grid development trends and the key technologies of power electronics. |
