A Passive harmonic filter (F) has an input node (B) for connection to a power supply (1), an output node (C) for connection to a load (15, 17) and an intermediate node (A). A first branch (3, 4) located between the input node (B) and the intermediate node (A) has at least one first inductance (4). A second branch (11, 13) located between the intermediate node (A) and the output node (C) has at least one second inductance (11). A third branch (5, 7, 9) is connected to the intermediate node (A) and has at least one capacitor (9). The first, second and third branch thus build a low-pass T-filter. A damping branch (22, 24) is provided having at least one first resistor (22), where the damping branch is arranged in parallel to the first branch. |
