Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0030] Such as figure 2 and image 3 As shown, the stacked common mode inductor in this embodiment includes two common mode inductors, the magnetic cores of the two common mode inductors are the same, the windings of the two common mode inductors are connected in series with the same number of turns, and the two common mode inductors are up and down Stacked together; where the cores of the two common-mode inductors are coaxially arranged; the winding directions between the two common-mode inductors are opposite. Of course, in other embodiments, four or more even-numbered common-mode inductors may also be set.
[0031] Further, the magnetic cores of the common mode inductors are arranged coaxially, and the windings of the common mode inductors are also arranged coaxially. The windings of each common mode inductor are uniformly wound on the c...
