| 摘要 |
<p>The invention relates to a circuit, wherein a power converter (1) of a motor is connected to a power supply network via its input connectors (2, 3) and in which at least one network condenser (CN) is parallel connected to the power converter (1) of the motor 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 one RC 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 is series connected thereto. At least one suction circuit choke (LSK) is series connected to the power choke (LN). The capacitor (CSK) forms a suction circuit with the suction circuit choke (LSK) in AC operation mode and an RC circuit (5, 6) with the resistor (R1, R2) in DC operation mode.</p> |
