There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

In the future smart grid, it is a significant trend to integrate large capacity renewable energy into medium voltage (MV) DC grids. The high power conversion techniques for wind generation, photovoltaic generation and hydrogen energy system integrated into MVDC grids are reviewed and compared in this lecture, including the system configurations, AC-DC and DC-DC converter designs, control strategies and fault protection. Novel solutions of DC grid-connected photovoltaic generation system are presented, providing new ways to integrate solar energy to DC grids with high efficiency and high power density. As the key element of high power isolated DC-DC converters, high frequency transformers with high withstand voltage are studied in terms of multi-physics modeling, magnetic integration, insulation design, thermal design and multi-objective optimization.
