Abstract

一种电感器以及相关装置，该电感器包括：一字型平行设置的上磁轭(101)和下磁轭(102)；第一绕线柱上设置第一绕组(107)；第二绕线柱上设置第二绕组(108)；上磁轭(101)、第一上绕线柱(103)以及第二上绕线柱(104)一体成型；下磁轭(102)、第一下绕线柱(105)以及第二下绕线(106)柱一体成型；第一绕组(107)中电流顺/逆时针方向与第二绕组(108)中电流顺/逆时针方向一致，使得第一绕组(107)在第一绕线柱中产生的直流磁通，与第二绕组(108)在第二绕线柱产生的直流磁通抵消。避免了因电感器中绕线柱的磁密过高而发生饱和时，引起的电流畸变的技术缺陷。使电感器能够承受瞬时过载功率而不饱和，提高了短时过载能力。上下磁轭和绕线柱可以采用一体成型技术，具有加工简单，电感器成品的感量一致性高等优点。
