Experimental evaluation of power router based on a fractionally-rated back-to-back converter at 13 kV 1MVA

There has been an increasing interest in development of power routers to realize dynamically controllable grid. Previously the authors have proposed a power router based on fractionally-rated BTB (FR-BTB) converter, which was shown to have reduced semiconductor and magnetics requirement compared to traditional power routing solutions. This paper presents the development and functional demonstration of the FR-BTB based power router at 13 kV, 1 MVA while reflecting on the challenges associated with high voltage and high power applications. The paper also presents applications of the power router in distribution systems.
