ルとコアの間に電位差による放電を発生させない。A U-shaped magnetic core 25 constitutes a square-shaped core. A primary coil on the input side uses a one-turn coil 21 and a one-turn coil 22, and a secondary coil on the output side uses a coil 23 and a coil 23. Use 24. As shown in FIG. 5, the connection method of the coil component of the present invention is as follows.
The turn coil 21 and the one-turn coil 22 are connected in series, and the input voltage Vin is applied substantially as a two-turn coil. In the secondary coil, the winding directions of the coil 23 and the coil 24 are different from each other. When each coil is viewed alone, the voltage of the coil 23 increases from terminal to terminal, and the voltage of the coil 24 decreases from terminal to terminal. I do. However, the secondary coil is connected as shown in FIG.
On the secondary side coil, the coil 23 and the coil 24 are configured as parallel coils. The coil a point where the secondary side coil 23 and the coil 24 oppose each other has the same voltage value, and also has the same voltage value at the coil b point. That is, the potential difference is close to zero in the opposing coils of the shortest distance between the coil 23 and the coil 24, and the right and left legs of the U-shaped core formed by combining the U-shaped cores can be used, and the volume of the U-shaped core is reduced. And made it possible to make it smaller than before. Further, by forming the secondary coil 23 and the coil 24 into a single-layer aligned winding, even if the boosted voltage value of the secondary coil is several tens of kV, the distance between the start and end of winding of the coil is sufficiently large. And the secondary coil 23
Since the potential difference is near zero at the coil opposing portion of the coil 24 and the shortest distance, no discharge occurs. Although not shown, the coils 21, 22, 23, and 24 are wound around a bobbin made of an insulating resin, and are insulated from the core, so that a discharge due to a potential difference between the coil and the core is not generated.

できる。[0008] Each of the primary coils is made of a conductor having a diameter of 0.8φ, and the secondary coil is formed of a UEW wire having a diameter of 0.2φ.
By winding five turns, a primary-side voltage of 1000 V to a secondary-side voltage of 20,000 V can be obtained. At this time, the square core is insulated by the thickness of the bobbin 6 and the flanges 8 and 9 with respect to the voltage of 20000 V of the secondary coil.
Further, since the primary side coil is located in the thick flange 8, insulation is obtained. In addition, since the coil is wound in a single-layer arrangement in the secondary coil, the potential difference between the layers of the coil is reduced, and the conventional discharge phenomenon does not occur. The opposing secondary coils 3 and 4 have the same voltage boosting direction, and the opposing coils 3 and 4 have the same number of turns, so that the voltage value for each coil turn is the same and the potential difference Small coils can be formed. In the figure, bobbins with different terminal positions are shown,
It is easy to make the bobbins to be incorporated into the left and right side legs of the core identical. In the embodiment, the U-shaped magnetic core is used.
Alternatively, an L-shaped core or a U-shaped or I-shaped core can be used as the core. Note that the primary side coil can also be connected in parallel, and in that case, the voltage value on the high voltage side in the above-described embodiment can generate 40000 V which is twice that of the embodiment.
