Abstract: A non-linear inductor is disclosed herein. The non-linear inductor includes a first magnetic core, a second magnetic core, a third magnetic core, a fourth magnetic core, a fifth magnetic core and a coil unit. The first and the second magnetic core are disposed in parallel. The third magnetic core, the fourth magnetic core and the fifth magnetic core are all vertically disposed between the first and the second magnetic core. The fourth magnetic core is vertically disposed between the first and the second magnetic core. The fourth and the fifth magnetic core are disposed at both sides of the third magnetic core in parallel. The coil unit winds around the third magnetic core. A magnetic resistance of the fourth magnetic core passed through by an inductive magnetic flux is different from a magnetic resistance of the fifth magnetic core passed through by the inductive magnetic flux.

Abstract: An integrated magnetic element is provided, including a first magnetic-core frame, three second magnetic-core frames, and three coil windings. The first magnetic-core frame has a first side pillar and a second side pillar opposite to the first side pillar. The three second magnetic-core frames are arranged on the side corresponding to the first side pillar of the first magnetic-core frame, and are arranged in parallel with the axis of the first side pillar of the first magnetic-core frame. Each of the second magnetic-core frames has a first side pillar adjacent to the first side pillar of the first magnetic-core frame, and a second side pillar opposite to the first side pillar of itself. The three coil windings connect to a three-phase grid, and wind around the first side pillar of the first magnetic-core frame and the corresponding first side pillar of the second magnetic-core frame respectively.
