论文摘要
本文介绍了一种设计方法的首次评估，旨在最小化$ n $的数量和气隙长度$ g $的基于铁核核心的低频电流偏置AC滤波器电感器。通过不同类型的铁氧体材料制成的功率模块（PM）芯的特定模型，并具有不同种类的气隙布置的特定模型，首先将相应获得的设计结果与经典方法进行比较，以计算$ n $和使用条纹因子来确定$ g $。接下来，就我们的设计方法讨论了在峰值电流下指定电感滚动及其潜在局限性的精致设计方法。最后，分析了超出其设计规范的电感器的行为。
This paper presents a first assessment of a design method aiming at the minimization of the number of turns $N$ and the air gap length $g$ in ferrite-core based low-frequency-current biased AC filter inductors. Several design cases are carried on a specific model of Power Module (PM) core, made of distinct ferrite materials and having different kinds of air gap arrangements The correspondingly obtained design results are firstly compared with the classic approach by linearization of the magnetic curve to calculate $N$ and the use of a fringing factor to determine $g$. Next, a refined design approach of specifying the inductance roll-off at the peak current and its potential limitations are discussed with respect to our design method. Finally, the behaviour of inductors operated beyond their design specifications is analyzed.
