Abstract (en)

[origin: WO2017148670A1] The invention relates to an efficient way to charge DC link capacitor in a charging circuit for an electric energy store. To this end, the DC link capacitor of the charging circuit is initially charged, by means of the charging circuit, to a voltage in the range of a voltage across the terminals of the electric energy store to be charged. The DC link capacitor is electrically connected to the electric energy store to be charged only once the DC link capacitor has been charged to the predefined voltage.
