(54)INTEGRATED MAGNETIC ELEMENTS


(57) 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.
