| 摘要 |
The invention relates to a current-compensated choke comprising at least two windings (W1, W2, W3), which are placed on a common core (1) and which each have an input (E1, E2, E3) and an output (A1, A2, A3), and comprising an additional auxiliary winding (WH) on the core (1), which has an input (EH) and an output (AH). According to the invention, a varying impedance (Z) is applied between the input (EH) and the output (AH) of the auxiliary winding (WH). The attenuation or saturation behavior of the choke can be adapted to a frequency or to a load by the varying impedance. |
