The medium-voltage (MV) connected charging station is proposed by the researchers to overcome the challenges regarding the conventional chargers by eliminating the line-frequency transformer and direct connection to the medium voltage. Different medium-voltage multilevel converters have been proposed to facilitate the direct connection to the MV grid. However, disadvantages such as a high number of components and control complexity weaken the strength of MV connected stations. This paper presents a new ultra-fast charging architecture that has fewer number components and a lower control complexity in comparison to existing solutions.
