基于高频母线的兆瓦级四端口电力电子变压器设计与实现

With high penetration of various distributed energy resources and dc loads in modern power system, ac/dc hybrid distributed grid attracts a lot of attention due to its compatibility. Aiming for interface of the ac/dc hybrid distributed grid, a four-port megawatt-level power electronic transformer (PET) is focused on in this article. A novel high-frequency-bus based multiport PET topology is propos...
