Abstract:
A filtering method for the alternating current side of a power conversion system by a filter circuit, and system that includes the filter circuit. Said filter circuit includes a filter capacitor circuit and a damping circuit connected to the filter capacitor circuit. Upon determining that the power conversion system operates under steady state conditions, the damping circuit of the filter circuit is caused to present a first impedance value for the current that flows through said damping circuit, and upon determining that the power conversion system is operating under transient state conditions, said damping circuit is caused to present a second impedance value for said current.

Claim (Index 26):
A power conversion system for converting energy from an alternating current or direct current power source, the power conversion system having an alternating current side and comprising,\n a power converter connected to an electrical grid; a filter circuit arranged at the alternating current side of the power conversion system, the filter circuit comprising a filter capacitor circuit; a damping circuit connected to the filter capacitor circuit and being configured to present a first impedance value for current that flows through said damping circuit when the power conversion system operates under steady state conditions, and to present a second impedance value for said current when the power conversion system operates under transient state conditions, the damping circuit comprising two alternative paths with different impedance values for the current that flows through said damping circuit, said current following a first path with the first impedance value or a second path with the second impedance value when the current flows through said damping circuit; and a selector configured to select one of the two alternative paths to cause said damping circuit to present the first impedance value or the second impedance value for said current that flows through said damping circuit according to the conditions under which the power conversion system is operating.
