LLC resonant transformer structure assembled by long and short magnetic cores

The utility model discloses an LLC resonant transformer structure assembled by a long magnetic core and a short magnetic core, which comprises a shell and a measuring coil positioned in the shell, the short magnetic core and the long magnetic core are symmetrically arranged on two sides of the shell, and middle column air gaps extending into the measuring coil are arranged on the sides, close to each other, of the long magnetic core and the short magnetic core. The LLC resonant transformer has the beneficial effects that the magnetic core is made into a long magnetic core and a short magnetic core which are assembled by adopting a long-short assembling structure, so that the position of a middle column air gap of the magnetic core is adjusted, and the leakage inductance required by the LLC resonant transformer can be met. Meanwhile, the leakage inductor can be used as a resonant inductor required by an LLC resonant converter circuit, so that the resonant inductor in the resonant converter circuit is saved, th
