The invention provides a magnetic-core-free planar transformer, a power module and a vehicle, the magnetic-core-free planar transformer comprises a plurality of substrates, a plurality of primary side coils and a plurality of secondary side coils, the substrates are sequentially stacked, each substrate comprises a winding area and at least one through hole, the winding areas are arranged around the through holes, the primary side coils are arranged around the through holes, and the secondary side coils are arranged around the winding areas. The plurality of primary side coils are respectively arranged in the winding areas of the different substrates, the plurality of secondary side coils are respectively arranged in the winding areas of the different substrates, the primary side coils and the secondary side coils are respectively arranged in the winding areas of the different substrates, any two adjacent primary side coils are connected through a primary side connecting line, and any two adjacent secondary side coils are connected through a secondary side connecting line. Any two adjacent secondary side coils are connected through a secondary side connecting line, and the secondary side connecting line and the primary side connecting line are arranged in different penetrating holes in a penetrating mode. Therefore, according to the planar transformer, a magnetic core arranged at the center position of the substrate of the planar transformer is reduced, so that the primary side coil and the secondary side coil do not need to avoid the magnetic core, and the size of the planar transformer is reduced.

    本申请提供一种无磁芯的平面变压器、电源模块及车辆,无磁芯的平面变压器包括多个基板、多个原边线圈和多个副边线圈,多个基板依次层叠设置,每个基板包括绕线区和至少一个穿孔,绕线区环绕穿孔设置,多个原边线圈分别设置于不同的基板的绕线区,多个副边线圈分别设置于不同的基板的绕线区,原边线圈和副边线圈分别设置于不同的基板的绕线区,任相邻两个原边线圈之间通过原边连接线相连,任相邻两个副边线圈之间通过副边连接线相连,副边连接线与原边连接线穿设于不同的穿孔。如此,本申请的平面变压器减少了设置于平面变压器的基板的中心位置的磁芯,使得原边线圈和副边线圈无需避让磁芯,从而有助于减小平面变压器的体积。
