Transformerless charging stations mean removing the LF transformer from stations to enhance the power density. Basically, for removing the LF transformer, the voltage level should be stepped down, there is the connection of the front-end converter, so we have two ways. The first way is a low-voltage grid used for supplying to the charging station.
