Beschreibung
Zusammenfassung:	The invention relates to a filtering method for the AC side (100a) of a power conversion system (100), using a filtering circuit (104), and to the system (100) comprising the filtering circuit (104). The filtering circuit (104) comprises a capacitive filtering circuit (6) and a damping circuit (1) connected to the capacitive filtering circuit (6). When the system (100) is detennined to be operating in steady conditions, the damping circuit (1) of the filtering circuit (104) provides a first impedance value for the current (i) circulating through the damping circuit (1) and through the capacitive filtering circuit (6), and when the system (100) is detennined to be operating in transient conditions, the damping circuit (1) provides a second impedance value for the current (i).
