摘要：The invention relates to a circuit, wherein a power converter (1) of a motor isconnected to a power supply network via its input connectors (2, 3) and in which at leastone network condenser (CN) is parallel connected to the power converter (1) of themotor and at least one power choke (LN) is series connected to the network condenser(CN). The power choke (LN) comprises at least one tapping point (4) in which at least oneRC circuit (5, 6) is parallel connected to the network condenser (CN) and the RC circuit (5,6) comprises at least one capacitor (CSK) as well as at least one resistor (R1, R2) that isseries connected thereto. At least one suction circuit choke (LSK) is series connected tothe power choke (LN). The capacitor (CSK) forms a suction circuit with the suction circuitchoke (LSK) in AC operation mode and an RC circuit (5, 6) with the resistor (R1, R2) in DCoperation mode.
