| Abstract: | Taking three-level DC/DC power conversion as the research object, this paper analyzes and compares topology structure. From the point view of modular engineering application, it develops three-level DC/DC standard power module based on improved half bridge type program, and introduces the structure and cabinet assembled way which can meet the power combination of plug and play and adapt to photovoltaic power generation, energy storage, electric vehicles and other application scene. The status of currently technology specification and standard is analyzed. The features of the DC/DC module in different application scenes are described and the experiments are carried out based on AC-DC hybrid microgrid test system. |
