[Abstract]:With the development of smart grid, the traditional distribution network structure, which is mainly composed of transformers and switches, will be changed, and the power conversion system will play a more important role and realize more systematic functions. Firstly, the research significance of power conversion technology in smart grid is discussed, on the basis of which, the limitation of traditional power conversion technology and the concept and development characteristics of new generation high-frequency isolation power conversion technology are comprehensively expounded. Secondly, the typical research projects of high frequency isolation power conversion technology at home and abroad are introduced from the system level, and the research progress of key technologies from the converter level is introduced. On this basis, the key problems need to be solved in the research of high frequency isolation power conversion technology at the technical level. At the same time, taking the high-frequency isolated solid-state transformer as a typical case, the application scheme of the new generation high-frequency isolation power conversion technology in the smart grid is discussed. Finally, according to the current situation of China's research, some suggestions for development are given.
