Zusammenfassung:	The disclosure relates to a method and a circuit for the improved use of a capacitance in an intermediate circuit. According to the disclosure, a change in a voltage in an intermediate circuit is detected and electrical energy is actively provided depending on the change in the electrical variable in order to compensate the change. According to the disclosure, a capacitance used in the intermediate circuit can end up significantly smaller if the electrical energy fed in is used, in that the voltage of the capacitance is supported by a current fed into the capacitance on the earth side.
