LLC resonant converter

The LLC resonant converter comprises a transformer winding and a resonant coil, the transformer winding comprises a primary winding and a secondary winding which are simultaneously wound along a firstaxis, at least one resonant coil passes through a coil center opening part of the transformer winding and the outer side of the transformer winding, and the secondary winding passes through a coil center opening part of the transformer winding and the outer side of the transformer winding. And the wire is wound along a second axis which is orthogonal to the first axis. Through the scheme of the utility model, the problem of high loss caused by integration of magnetic elements can be effectively solved, and the transformer winding and the resonance coil can share the same magnetic core, so that the LLC resonant converter is favorable for realizing the design of high power and miniaturization at the same time. 一种LLC谐振变换器，包括变压器绕组和谐振线圈，所述变压器绕组包括同时沿第一轴线缠绕的初级绕组和次级绕组，所述谐振线圈至少一个，通过所述变压器绕组的线圈中心开口部及所述变压器绕组的外侧，沿与所述第一轴线呈正交方向
