In Figure 7, the role of such a transformer is as follows. When the sine wave voltage is input once to transformer 1 At the time of winding 3, magnetic flux can be generated in the central magnetic leg 6 by electromagnetic induction. This magnetic flux will pass through the 'magnetic path' formed by the magnetic core, induce the electromotive force to the secondary winding 4, and output it from the secondary winding 4. Sine wave voltage. The ratio of the input sine wave voltage to the output sine wave voltage is proportional to the turns ratio of the number of turns of the primary winding 3, < and the turns of the secondary winding, Therefore, by appropriately adjusting the turn ratio and the voltage 値 of the input sine wave voltage, it can produce an output voltage with an arbitrary voltage 产生. This paper scale is applicable to China's standard (CNS) A4 ^ (210 · 〆 297mm) Printed by A7 B7, Shellfish Consumer Cooperative of the Central Bureau of Samples of the Ministry of Economic Affairs 5. Description of the Invention (4) [Questions to be Solved by the Invention] The competition was “at the time when the miniaturization of the transformer was attempted without changing the characteristics”. The size of the effective cross-sectional area of the magnetic flux will form an important factor. The voltage 値 related to the input voltage applied to the primary winding, and the magnetic 逋 density and core of the core induced (induced) by the input voltage. The product of the effective cross-sectional area of the magnetic flux has a proportional relationship. Furthermore, the product of the magnetic flux density induced by the input core and the effective cross-sectional area of the magnetic core and the output voltage induced by the secondary winding There is a proportional relationship between the voltages 。. If the effective cross-sectional area of the magnetic core is reduced, the magnetic core will become small, and with this situation, although the overall size of the cold transformer can be miniaturized, When the flux density is assumed to be constant, the magnetic flux passing through the core will be reduced, and the above-mentioned proportional relationship will limit the voltage that can be input and output to the transformer. Therefore, if the effective cross-sectional area of the magnetic core is to be maintained and the transformer is to be thinned, the shape of the magnetic (path) diameter of the magnetic core must be flat. For this reason, if the winding is wound on the core without changing the number of turns, the length of the winding will become long, so that it has the so-called increased copper loss, while increasing the leakage magnetic flux, and reducing the power of the transformer. The issue of (power) transmission efficiency. In the structure of the conventional transformer, in order to insulate the magnetic core and the primary winding and the secondary winding, it is necessary to use (coil) coils. Because of the existence of the coils, it is necessary for the entire volume of the transformer.

Description of the invention (8), the insulating material 4 5 for the winding can also be arranged from the middle magnetic leg 36 to the side magnetic core 3 g to form a parallel shape with the outer magnetic leg. At this time, the primary winding 34 and the secondary winding 35 will be isolated by the insulating material 45 for the winding. In FIGS. 3 and 4, the organic resin film 41 covers the winding grooves of the main magnetic core 32. The inner surface 4 0 of the main magnetic core 3, and the secondary winding 3 5 is wound around the entire surface of the intermediate magnetic leg 36, and the secondary winding 35 is wound around the entire surface. The winding 3 5 is covered with an insulating material 4 2 for winding, and the winding 3 4 is wound around the insulating material 4 2 for winding once in a laminated shape. That is, the primary winding 34 and the secondary winding 35 are insulated by an insulating material for the winding. ~ The secondary winding 3 4 and the secondary winding 35 are copper wires covered with polyurethane. When the wire diameter of these windings is small, the cross-sectional area of the winding will be small and the number of turns can be increased. However, when the wire diameter is too small, the current flowing in the winding will increase the copper loss. To determine the most suitable wire diameter, the number of turns required, the cross-sectional area of the winding receiving groove, and the current flowing in the winding should be considered. Printed by the Central Standards Bureau of the Ministry of Economic Affairs and Consumer Affairs Co., Ltd. (Please read the precautions on the back before filling out this page) When the number of windings is large, although it is wound in several layers, it should be used for The width of the winding receiving groove 38 is to form a tight and uniform winding. As shown in Figs. 5 and 6, it is preferable that the terminals 49 of the primary winding and the terminals 50 of the secondary winding are separated as much as possible. More ideally, the terminals 49 and 50 of the primary winding and the secondary winding are individually pulled out in the direction of the long axis of the transformer 31, which is better.

The thickness of 3 7 is equal to the thickness of the side magnetic core 3 3, and the thickness of the middle magnetic leg 36 is about twice the thickness of the outer magnetic leg. When it is configured as such, the magnetic core 3 can be passed through The effective cross-sectional area of the magnetic flux of 2, 3 3 will be uniformly uniform in any part of the magnetic core 3 2, 3 3. In Figs. 5 and-6, the thickness of the outer magnetic leg 37 or the side magnetic core 3 is assumed. The thickness of 3 is taken as a, and the direction parallel to the winding groove 38 of the transformer 31 is taken as the length of the transformer, and assuming that it is b ', the effective sectional area S of the magnetic flux becomes S = 2ab. Therefore, The effective cross-sectional area of the magnetic flux will be determined by the thickness of the middle magnetic foot 36 and the thickness of the outer magnetic foot 37. The thickness of 3 3 and the length of the transformer are determined. For this reason, in the structure of the transformer 31, it is attempted to narrow the width of the transformer 3 1 and reduce the thickness, unless the middle leg 3 of the main core 3 2 is made In addition to the thickness of the outer magnetic leg 37 or the side magnetic core 33, or to shorten the length of the transformer 31, the effective cross-sectional area of the magnetic flux can be maintained as it is. Therefore, the output and input voltages will not be affected. The voltage 値 becomes restricted. When considering the strength of the ferrite material as the material of the main core 32 and the side core 33, the thickness and side of the magnetic foot 3 7 other than the main core 3 2 The thickness of the magnetic core 33 is preferably 1 mm or more. Almost all parts of the secondary winding 3 4 and the secondary winding 'form a structure surrounded by the main magnetic core 3 2 and the side magnetic core 3 3' for this purpose '. This structure is even in the narrow width of the transformer 31 which is attempted to be thin. It will not change, so the leakage magnetic flux becomes very small, and it can get very high.

Description of the invention (10) Coefficient. #, While maintaining the effective cross-sectional area of the magnetic flux and making the transformer 3 1 ′ thin, only the height of the main magnetic core 3 2_ and the width of the side magnetic core 33 are reduced, and not even Changing the number of turns to wind the windings 34, 35 for the intermediate magnetic leg 36 will not cause a large change in the length of the windings 34, 35, so it will not increase the copper loss. Therefore, the transformer 3 1 of the invention The magnetic flux leakage is small, and copper loss will not be increased. Therefore, even if the narrow width and thinness of the transformer 31 are attempted, it will not reduce the transmission efficiency of the electric side. In the structure of the transformer 31 of the present invention, the volume occupied by the organic resin film 41 is small, and the area occupied by the cores 32, 33 or the windings 34, 35 with respect to the entire volume of the transformer 31 can be increased. Effective use of space. When the transformer 31 is used, although heat is generated in the main magnetic core 32, the side magnetic core 33, and the primary and secondary windings 3 4, 35, as mentioned above, the volume occupied by the organic resin film 41 is extremely small due to the extremely small volume. Therefore, the heat generated is not stored. Furthermore, the materials of the main magnetic core 32 and the side magnetic core 3 3 are magnetic bodies having extremely high thermal conductivity, and therefore, the generated heat can be released to the outside of the transformer 31 with high efficiency. Also used as the material of the main magnetic core 3 2 and the side magnetic core 3 3, if using the Mn F e polycrystalline iron with crystal grain size 1 ~ 5 as described in Japanese Patent Laid-Open No. 5 \ -2 4 3 0 3 2 In the case of oxygen, the loss in the magnetic cores 3 2, 3 3 can be reduced, and the heat generated by the magnetic cores 3 2, 3 3 can be suppressed. Since such an effect can be achieved, the safety of the transformer 31 can be ensured.

Description of the invention (彳 彳) Another winding 3 4 and the secondary winding 3 5 are for the width of the winding groove 38; to form a tight and uniform winding, so that the potential difference between adjacent windings can be reduced; Furthermore, the transformer 'for this' is constituted by separating the terminals 49 of the primary winding and the terminals 50 of the secondary winding as much as possible, thereby preventing damage to the insulation. Further, in the structure of the transformer 31 of the present invention, the number of parts can be reduced, so that the manufacturing cost of the transformer 31 can be reduced. In addition, although the main magnetic core 3 2 is made of millstone to process M η Z η ferrite blocks to form winding grooves 38, it can also be filled with ferrite powder in a mold and press-molded, and given Fired to make. When manufactured in this manner, the groove width and groove depth of the machinable winding groove 38 are the cross-sectional areas required for the winding. As for the space required for the winding, if the groove width is 2 mm and the groove depth is 1.5 mm, the overall size of the transformer 31 can be 7 mm wide and 4 mm high.

Description of the invention (12) Insulation material for winding 42, 45. It is most suitable to use a resin having a high insulation property and a low dielectric constant, preferably a film of polyimide, polyvinyl chloride, polyethylene polyester, fluororesin, epoxy resin, or the like. These resins have a sufficiently small electric induction rate in the range of 2 to 4, and are excellent in insulation properties. When the number of windings is large, it is also possible to sandwich an insulating material between the layers of the windings. Furthermore, a gap may be provided at the joint surface of the main magnetic core 32 and the side magnetic core 33 for the purpose of suppressing magnetic saturation and adjusting the inductance 値. The gap is formed by sandwiching an insulating material such as resin. The adjustment of the gap is to fix the gap between the main magnetic core 32 and one side magnetic core 33, and to adjust the gap with the other side magnetic core 33 to easily adjust the magnetic characteristics. The insulation material to be used in the gap is preferably as small as possible, such as resins with electrical properties. Films of polyimide, polyvinyl chloride, polyethylene, polyester, fluororesin, epoxy resin, etc. are preferred. . These resins have a sufficiently small electric induction rate in the range of 2 to 4, and therefore can be appropriately selected from these and used.

With the structure as described above, a transformer having an overall size of \ width 8mm, length 18mm, and height 4.5mm is assembled as shown in Fig. 4. [Comparative example] Assembled with a width of 14.2mm and a length of paper as shown in Fig. 7 Chinese National Standard (CNS) A4 (210X297 mm) -16- Economic & Military Consumption " Cooperative printed poly A7 _B7_ V. Description of the invention (14) 18.3 in., 5.38 mm height transformer with E-shaped core. The turns ratio is one time: two times = 14: 1520, which can be boosted by about 108 times! Next, the transformer characteristics of the embodiment will be described. Figure 9 shows that the secondary winding is opened, and the impedance analyzer includes the copper loss and iron loss, etc. 値 resistance R, equal-値 inductance L, system coefficient Q (= WL / R). Also in Fig. 10, the equivalent resistance R, equivalent inductance L, and the coefficient of state Q (= W L / R) including copper loss and iron loss measured by the impedance analyzer with the primary winding open will be shown. Although the transformer of the embodiment has a smaller width and height and a smaller turn ratio than the transformer of the comparative example, the inductance is high and the resistance 値 formed by the windings is small. Therefore, even if the transformer of the present invention is miniaturized, it does not reduce the power transmission efficiency. Figure 11 is a measurement system showing the boost ratio and power (power) transmission efficiency. The sine wave voltage of frequency 5 7KHZ generated by the function wave generator 60 is amplified by the power amplifier 61 and a predetermined voltage 値 sine wave is applied to the primary winding of the transformer 62. Fig. 12 shows the step-up ratio of the transformer of the present invention to the secondary voltage of the primary voltage when the secondary winding is opened. Since the voltage increase is approximately equal to 83 times of the turns ratio of the primary winding and the secondary winding (approximately 8 3, 3 times), it can be found that the leakage magnetic flux is very small, showing the primary winding and the secondary winding. The windings form an excellent magnetic coupling. Figure 13 shows the connection of the load resistance to the terminal of the secondary winding of the transformer and a sinusoidal AC voltage with an input frequency of 5 7KH z.

From the results as described above, it has been proved that even a so-called narrow transformer with a width of 8 mm and a height of 4.5 mm and a thin transformer can obtain good characteristics if it is constituted as the structure of the present invention. [Effects of the invention] Printed by the Central Standards Bureau of the Ministry of Economic Affairs of Beiya Consumer Cooperatives (please read the precautions on the back before filling out this page) As detailed above, the transformer of the present invention is provided with a magnetic body The main magnetic core, the side magnetic core formed by the magnetic body joined to the two ends of the main magnetic core, and the primary winding and the secondary winding to be assembled to the main magnetic core, and the main magnetic core is composed of an intermediate magnetic leg. And formed on one end and the other end of the middle magnetic foot and extending to one outer magnetic foot in a direction orthogonal to the middle magnetic foot, and between the one outer magnetic foot and the two outer magnetic foot The winding grooves sandwiched between the middle magnetic leg and the middle magnetic leg are formed on both sides of the middle magnetic leg, and the primary winding and the secondary winding pass through two winding grooves, and are configured to wind the aforementioned middle magnetic leg. Almost all the parts forming the winding are surrounded by a magnetic core structure, so that the leakage magnetic flux becomes a small 'copper paper' standard applicable to the Chinese National Standard (CNS > A4 specification (210 × 297 mm) -18- Staff Consumption of the Central Standards Bureau of the Ministry of Economic Affairs Cooperative printed poly A7 B7 V. Description of the invention (16) The loss is reduced, so that the power transmission efficiency can be reduced. Because the transformer of the present invention adopts the above-mentioned structure, 'unless the main magnetic core; the middle magnetic leg of the heart, The thickness of the outer magnetic leg and the side magnetic core becomes thinner or the length of the transformer is shortened, and the effective cross-sectional area of the magnetic flux can be maintained as it is. Therefore, it does not cause the voltage to be input and output to the transformer to be limited, so that it does not decrease. In order to reduce the width and thickness of the transformer under the power transmission efficiency, the material of the main core and the side core is a magnetic body with high thermal conductivity, so that it can be efficiently released in the main core and the side core. And the heat generated by the primary and secondary windings is external to the transformer, so the safety of the transformer can be ensured. In the transformer of the present invention, the side magnetic core is connected to one of the main magnetic cores at the front end of the outer magnetic leg to be connected to the foregoing. The main core is clamped by an external magnetic leg to be joined to the main core. Therefore, it is easy to join the cores to each other and the transformer can be simply assembled, so that The manufacturing cost can be reduced. Furthermore, a gap can be provided at the joint portion, so a transformer with desired characteristics can be easily manufactured. The transformer of the present invention, the secondary winding is fully wound around the intermediate magnetic leg, Furthermore, the primary winding 34 is wound by being laminated on the secondary winding, so that once, the insulation between the secondary windings becomes high, and a transformer with extremely high withstand voltage can be obtained. The transformer of the present invention, The primary and secondary windings are arranged so as to separate the windings of the aforementioned intermediate magnetic feet from the above-external magnetic feet to form individual windings. Therefore, when the transformer is manufactured, it can be wound at the same time as the secondary windings.

Description of the invention (17) and the secondary winding to make it possible Simplify the manufacturing process of the transformer, which can reduce the manufacturing cost of the transformer. Furthermore, the transformer of the present invention is coated with an organic resin film on the inner surface of the winding groove of the main magnetic core, and is wound once and the secondary winding is wound thereon. Therefore, the volume occupied by the organic resin film is small, making it possible Increase the core of the entire volume of the transformer-or the volume occupied by the primary and secondary windings, so space can be effectively used. In addition, the organic resin film has a small volume, so that it can be dissipated without storing the heat generated by the transformer. Therefore, the safety of the transformer can be ensured. Furthermore, the transformer of the present invention can be used because the number of parts is small. Reduce the cost of transformers.
