    • An inverter transformer capable of driving two straight tubs to inphase is provided to reduce size of magnet core part by using a first core part as a core member forming a first magnetic path and a second magnetic path. A magnet core part(4) comprises a first core part(44), a second core part(45), a third core part(46), one end side connection core part(47), and other end side connection core part. The first core part is arranged on an axis line(C1) of a primary winding(1), and penetrates an inner part of the primary winding. A second core part is arranged on an axis line(C2) of a first secondary winding(2), and penetrates an inner part of the first secondary winding. A third core part is arranged on an axis line(C3) of a second secondary winding(3), and penetrates an inner part of the second secondary winding. The one end side connection core part connects one ends of the first to the third core part. The other end side connection core part connects the other ends of the first to the third core part. At least one side of the one end side connection core part and the other end side connection core part is made of a core member.
    • 提供能够同时驱动两个直槽的逆变器变压器,以通过使用形成第一磁路和第二磁路的第一芯部作为芯构件来减小磁芯部的尺寸。 磁芯部分(4)包括第一芯部(44),第二芯部(45),第三芯部(46),一端侧连接芯部(47)和另一端侧连接芯部。 第一芯部布置在初级绕组(1)的轴线(C1)上,并穿过初级绕组的内部。 第二芯部布置在第一次级绕组(2)的轴线(C2)上,并穿透第一次级绕组的内部。 第三芯部布置在第二次级绕组(3)的轴线(C3)上,并穿透第二次级绕组的内部。 一端侧连接芯部将第一芯部与第三芯部的一端连接。 另一端侧连接芯部连接第一至第三芯部的另一端。 一端侧连接芯部和另一端侧连接芯部的至少一侧由芯部构成。

    • An inverter transformer is provided to prevent a magnetic flux from leaking to an outside of the inverter transformer. In an inverter transformer, a first coil and a second coil are wound on the same axis by a plurality of coil bobbins(12a,12b) as being separated from each other. At least one core from a pair of cores(24a,24b) includes a plurality of core foot portions(24f,24g,24h) with the same number as the number of the coil bobbins(12a,12b). The pair of cores(24a,24b) come in contact with each other by inserting the core foot portions(24f,24g,24h) into the coil bobbins(12a,12b). And, the pair of the cores(12a,12b) form a closed magnetic path to connect the plurality of coil bobbins(12a,12b).
    • 提供逆变器变压器,以防止磁通量泄漏到逆变变压器的外部。 在逆变器变压器中,第一线圈和第二线圈由彼此分离的多个线圈线轴(12a,12b)缠绕在同一轴线上。 来自一对铁心(24a,24b)的至少一个铁芯包括与线圈架(12a,12b)的数量相同数量的多个铁芯脚部(24f,24g,24h)。 通过将芯脚部分(24f,24g,24h)插入到线圈筒管(12a,12b)中,一对芯体(24a,24b)彼此接触。 并且,一对芯体(12a,12b)形成闭合的磁路以连接多个线圈架(12a,12b)。
