如圖1-4,在本創作實施例中,圓角長方體R1_n和R2_n的組合作為繞線的柱體,由於兩側是曲面,對於繞制扁平線的利用率高,繞線體積也小,磁路的截面積也能達到最大面積利用,磁塊間的氣隙能自由調整,有利於對於電感整體的抗直流偏置能力提高。As shown in Figure 1-4, in this creative embodiment, the combination of rounded rectangular parallelepipeds R1_n and R2_n is used as the winding cylinder. Since the two sides are curved surfaces, the utilization rate for winding flat wires is high, and the winding volume is also small. The cross-sectional area of the magnetic circuit can also reach the maximum area utilization, and the air gap between the magnetic blocks can be adjusted freely, which is beneficial to the improvement of the overall anti-DC bias ability of the inductor.
圓角長方體R1_n和R2_n的軟磁材料可以全部使用初始磁導率u一樣的粉芯磁芯材料,也可以使用初始磁導率u不同的磁芯材料,這樣可以按照需求調整橢圓柱體的整體磁阻,搭配起來後可以獲得標準磁材料之外的組合磁導率。而長方體C1_n和C2_n由於磁路的磁阻方向,它們對應的軟磁材料必須全部使用初始磁導率一樣的粉芯磁芯材料,這樣才能保證磁通的均勻分佈。The soft magnetic materials of the rounded rectangular parallelepiped R1_n and R2_n can all use powder core materials with the same initial permeability u, or core materials with different initial permeability u, so that the overall magnetic of the elliptical cylinder can be adjusted as required Resistance, after being matched, can obtain the combined permeability outside the standard magnetic material. The cuboids C1_n and C2_n must be made of powder core materials with the same initial permeability due to the magnetic resistance direction of the magnetic circuit, so as to ensure the uniform distribution of magnetic flux.
