Zusammenfassung:	According to an aspect of the invention, a precharging circuit for precharging an intermediate circuit capacitor (24) of a converter (14) formed from at least one electrolytic capacitor using a grid current from a supply grid 2 before the converter (14) is connected to the supply grid 2 and is used for the reformation of at least one electrolytic capacitor of the intermediate circuit capacitor (14). According to a further aspect of the invention, a method is provided for the reformation of an intermediate circuit capacitor (24) of a converter (14) formed from at least one electrolytic capacitor, which is connected to the supply grid 2 using a precharging circuit (29). According to yet another aspect of the invention, a converter (14) is created for converting an AC grid voltage into a direct voltage or vice versa, with a device for the reformation of electrolytic capacitors of an intermediate circuit capacitor (24) of the converter (14) using an integrated precharging circuit (29) of the converter (14). Advantageously, existing hardware can be used for the reformation of electrolytic capacitors in a converter, and the expense associated with the reformation can be minimized.
