Key Technologies and Development Trends of DC-DC Converters in Smart Grid Applications

As important parts that can realize efficient energy conversion and control in power electronic system, the DC-DC converters become more and more important with the continuous development of smart grid technology which are widely used in smart grid system. This paper performs a review of the main technologies, development trends in smart grids to comprehensively examine the types of technologies, operational principles, usage conditions, development status of these devices. First of all, an introduction to the basic principle and types of DC-DC converters both non-isolated as well as isolated converters. Also is it about applicable areas for each type. afterward, the paper will show some applications of the DC-DC converters to the smart grid like integration of distributed energy resources, Energy Storage Systems, EV chargers, etc. to prove the converters will help improve flexibility, reliability, and energy efficiency of the grid. The article carries out an analysis of the main technologies of the DC-DC converter and shows the role played by the converter in the system. Finally, after this review, this paper wants to give a certain amount of theoretical basis and technical references to those who are engaged in a similar field of work, and at the same time, this paper also hope that this research can help with the development of Dc—Dc converters used in smart grids.
