Abstract

The object of the invention is a method for controlling an AC/DC converter for an electric vehicle charging station, stabilising voltage in a DC circuit under voltage dip conditions during reduced capacitance in a DC link. A method for controlling an AC/DC converter for electric vehicle charging stations, stabilising voltage in a DC circuit under voltage dip conditions during reduced capacitance in a DC link constituting the first conversion stage of a converter power module CPM, with reduced capacitance CDC in the direct current link DC_link, for applications in electric vehicle charging stations DC_EVCS, involving the determination of reference currents Iref,αβ using the method of symmetrical components, characterised in that the reference currents Iref,αβ are determined in the control system, and the negative sequence component of the measured power grid voltage Uconv is modified by introducing factors k, m and r allowing for arbitrary shaping of the converter current Iconv.
