Abstract
A filtering arrangement for a system including a power electronics device and an external power storage/discharge element, which power electronics device includes a power module and a three-phase filter between the AC power terminals of the power module and the supplying AC power grid, and which power module includes a DC intermediate power bus, and which three-phase filter between the AC power terminals and the supplying AC power grid includes two three-phase inductors, and which external power storage/discharge element has two DC power terminals which are connected to the DC intermediate power bus of the power electronics device. The filtering arrangement includes a common mode inductor which is connected between the DC power terminals of the external power storage/discharge element and the terminals of the DC intermediate power bus of the power module.
