    • An inductive component (1a..1e) with at least two coils (2..4b) in a closed main magnetic circuit (5a..5j) for guiding a magnetic main flux (Φ H ) penetrating all coils (2..4b) is specified. The inductive component furthermore comprises a leakage field guide component (6a..8c) or a plurality of leakage field guide components (6a..8c), wherein a leakage field guide component (6a..8c) is arranged between two coils (2..4b) in each case, separated by two air gaps (E..J) from the main magnetic circuit and intended for guiding a magnetic leakage flux Φ S different from the main flux Φ H . The main magnetic circuit (5a..5j) and/or the leakage field guide components (6a..8c) consist of a magnetically isotropic material. Furthermore, the invention relates to a use of a choke (1a..1e) with a leakage field guide component (6a..8c) for guiding a leakage flux (Φ S ) arising in the choke (1a..1e) as a PFC (Power Factor Correction) choke.
    • 在用于引导穿过所有线圈(2..4b)的磁主磁通(PhiH)的封闭主磁路(5a..5j)中具有至少两个线圈(2..4b)的电感分量(1a..1e) 被指定。 感应部件还包括泄漏场引导部件(6a..8c)或多个泄漏场引导部件(6a..8c),其中泄漏场引导部件(6a..8c)布置在两个线圈(2 在每种情况下,由主磁路分离出两个气隙(E..J),用于引导与主通量PhiH不同的漏磁通PhiS。 主磁路(5a..5j)和/或泄漏场引导部件(6a..8c)由磁各向同性材料构成。 此外,本发明涉及一种具有泄漏场引导部件(6a..8c)的扼流圈(1a..1e)用于引导在扼流圈(1a..1e)中产生的漏电流(PhiS)作为PFC (功率因数校正)扼流圈。
