It needs to be thin so that it can be installed in a narrow gap. For this reason, the bobbin 2 has a flat rectangular cross section, and even if the number of turns is the same, the winding length becomes long, the conductor resistance increases, and the efficiency decreases. In the conventional rectangular transformer, the base is mounted under the bobbin and the core, so the thickness is limited to about 5 mm, and there is a problem that if the thickness is further compressed to increase the width, copper loss increases remarkably. . In addition, since the secondary winding L 2 has to be divided and wound, the winding work is complicated and the entire volume is increased.

Two through holes 42 communicating with the recess 41 are formed on the upper surface of the cover 40.
The outer winding 50 is mounted on the base portion 11 of the bobbin 10 while being housed in the recess 41 of the cover 40. In addition, the outer winding 50 is incorporated into the bobbin 10 in the concave portion of the cover 40 in which the outer winding 50 which has been wound and solidified is inverted.
This can be easily done by putting the bobbin 10 on which the inner winding 30 is wound upside down after putting it in the inner space 41 and inserting the inner winding 30 portion into the through hole 45.

Is a flat plate portion 71 and outer legs 72 integrally formed at both ends thereof, and a cylindrical center leg 73 integrally formed at the center of the flat plate portion 71.
The center leg 73 is inserted into the hollow portion of the winding shaft 12. Although illustration is omitted, magnetic saturation can be prevented by inserting the plastic film 80 or providing a gap between the core 60 and the center leg 73 or between the core 60 and the center leg 73 and the outer leg 72. It has a structure that makes it hard to get up. Bobbin 10
As shown in FIG. 5, a concave portion 17 sandwiched between the thick portions 16 on both sides is formed on the lower surface of the concave portion 17, and the flat plate portion 71 of the lower core 70 is fitted into the concave portion 17.

ばよい。As shown in FIG. 7, when the wire rod 8 is wound in multiple layers in the direction of the arrow, the winding start portion and the winding end portion of the next layer are adjacent to each other. However, in the above transformer structure, even if the voltage applied to both ends of the outer winding 50 is 2 kV, if the outer winding 50 is wound in 40 layers, for example, the voltage applied between the two is 2000 ÷ 20, which is 100 V. Therefore, similarly to the conventional example in which the secondary winding L 2 is divided into a plurality of stages and wound by the collar, the potential difference between the overlapping wire rods is reduced and dielectric breakdown is prevented. Some booster transformers for inverters have a low voltage on the high voltage side winding.
Although there is a voltage of 00 V or less, the height H of the outer winding 50 may be reduced and the winding width W may be increased in order to prevent dielectric breakdown.

場合は一次巻線に数１０ｋＨｚの大振幅共振電流が流れ

に大きく寄与できる要因となる。It is also possible to use E-shaped cores having the same shape as the pair of cores and to have the center legs of both cores butted against each other in the winding shaft 12 of the bobbin 10. The shape of a round transformer that winds a wire around a winding shaft with a circular cross section is shorter than that of a rectangular transformer, so the copper loss is reduced when achieving the same performance with the same magnetic material. It is advantageous in that the volume can be reduced. In particular, when used as an inverter transformer, a large amplitude resonance current of several tens of kHz flows in the primary winding, and therefore reduction of copper loss in the primary winding is a factor that can greatly contribute to improvement in conversion efficiency of the transformer.
