Please refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is the three-dimensional exploded view of the transformer 1 according to one embodiment of the invention, and Fig. 2 is the exploded side schematic diagram of the transformer 1 of Fig. 1, and Fig. 3 is the schematic side view of the transformer 1 of Fig. 1.As shown in Figure 1, transformer 1 comprises the isolated sheet 12 of a magnetic conduction core 11, one and an electric-conductor 13.It is peripheral that isolated sheet 12 is coated on magnetic conduction core 11.Electric-conductor 13 is wound around isolated 12 coated magnetic conduction cores 11.Isolated sheet 12 can be paper web or the scraps of paper.Completely cut off sheet 12 between magnetic conduction core 11 and electric-conductor 13, with magnetic conduction core 11 and the electric-conductor 13 of being electrically insulated.
Electric-conductor 13 comprises one first conducting strip 131,1 second conducting strip 132,1 first dielectric film 134 and one second dielectric film 135.First conducting strip 131 has one first relative inner surface 131a and one first outer surface 131b, and is positioned at relative 2 first lateral margin 131c therebetween.Second conducting strip 132 has one second relative inner surface 132a and one second outer surface 132b, and is positioned at relative 2 second lateral margin 132c therebetween.First inner surface 131a and the second inner surface 132a is all towards magnetic conduction core 11.First dielectric film 134 is attached at the first outer surface 131b and is coated on the relative 2 first lateral margin 131c of the first conducting strip 131.Second dielectric film 135 is attached at the second outer surface 132b and is coated on the relative 2 second lateral margin 132c of the second conducting strip 132.By this, in the first conducting strip 131 and the second conducting strip 132 mutually storehouse time, be electrically insulated each other.In other embodiment, the first dielectric film 134 and the second dielectric film 135 also can be attached at the first inner surface 131a and the second inner surface 132a respectively.In addition, in other embodiment, if better insulating properties will be had in order to make between the first conducting strip 131 and the second conducting strip 132, first dielectric film 134 also both can be attached at the first outer surface 131b and also be attached at the first inner surface 131a, and the second dielectric film 135 also both can be attached at the second outer surface 132b and also be attached at the second inner surface 132a.
In the schematic diagram of Fig. 2, because the thickness of the first dielectric film 134 shown in Fig. 1 and the second dielectric film 135 can be very thin, therefore ignore and do not paint.As shown in Figure 2, the first conducting strip 131 and the second conducting strip 132 have different length, but the two also can have identical or close length in other embodiment.In the present embodiment, the length of the first conducting strip 131 is greater than the length of the second conducting strip 132.When electric-conductor 13 is not yet wound around magnetic conduction core 11, the first conducting strip 131 and the second conducting strip 132 storehouse mutually, and the second outer surface 132b of the second conducting strip 132 is towards the first inner surface 131a of the first conducting strip 131.Second conducting strip 132 can be positioned over the middle position of the first conducting strip 131, also can offset to some extent.Electric-conductor 13 is wound around isolated 12 coated magnetic conduction cores 11 according to the winding direction R of Fig. 2.

Please refer to Fig. 5, Fig. 6 and Fig. 7, Fig. 5 is the three-dimensional exploded view of the transformer 2 according to another embodiment of the present invention, and Fig. 6 is the exploded side schematic diagram of the transformer 2 of Fig. 5, and Fig. 7 is the schematic side view of the transformer 2 of Fig. 5.As shown in Figure 5, similar with the transformer 1 of Fig. 1, the transformer 2 of the present embodiment also comprises the isolated sheet 22 of a magnetic conduction core 21, one and an electric-conductor 23.
But in the present embodiment, electric-conductor 23 comprises one first conducting strip 231,1 second conducting strip 232, the 3rd conducting strip 233,1 first dielectric film 234,1 second dielectric film 235 and one the 3rd dielectric film 236.3rd inner surface 233a of the first inner surface 231a of the first conducting strip 231, the second inner surface 232a of the second conducting strip 232 and the 3rd conducting strip 233 is all towards magnetic conduction core 21.First dielectric film 234 is attached at the first outer surface 231b of the first conducting strip 231 and is coated on the relative 2 first lateral margin 231c of the first conducting strip 231.Second dielectric film 235 is attached at the second outer surface 232b of the second conducting strip 232 and is coated on the relative 2 second lateral margin 232c of the second conducting strip 232.3rd dielectric film 236 is attached at the 3rd outer surface 233b of the 3rd conducting strip 233 and is coated on relative 2 the 3rd lateral margin 233c of the 3rd conducting strip 233.By this, in the first conducting strip 231, second conducting strip 232 and the 3rd conducting strip 233 mutually storehouse time, be electrically insulated each other.
In the schematic diagram of Fig. 6, because the thickness of the first dielectric film 234, second dielectric film 235 shown in Fig. 5 and the 3rd dielectric film 236 can be very thin, therefore ignore and do not paint.As shown in Figure 6, the first conducting strip 231, second conducting strip 232 and the 3rd conducting strip 233 have different length, but three also can have identical or close length in other embodiment, or in three wherein the two there is identical or close length.In the present embodiment, the length of the first conducting strip 231 is greater than the length of the second conducting strip 232, and the length of the 3rd conducting strip 233 is between the length of the first conducting strip 231 and the length of the second conducting strip 232.When electric-conductor 23 is not yet wound around magnetic conduction core 21, the second conducting strip 232 and the second conducting strip 333 arrange along a length direction LD of electric-conductor 23, and respectively with the first conducting strip 231 storehouse mutually.Second outer surface 232b of the second conducting strip 232 and the 3rd outer surface 233b of the 3rd conducting strip 233 is all towards the first inner surface 231a of the first conducting strip 231.Electric-conductor 23 is wound around isolated 22 coated magnetic conduction cores 21 according to the winding direction R of Fig. 6.
As shown in Figure 7, electric-conductor 23 is wound around magnetic conduction core 21, and makes the first conducting strip 231, second conducting strip 232 and the 3rd conducting strip 233 around magnetic conduction core 21.Electric-conductor 23, in the process being wound around magnetic conduction core 21, can be stacked over the part that electric-conductor 23 self had previously been wound in magnetic conduction core 21.Therefore, relative two of one of them section of the second conducting strip 232 can be located in different two sections of the first conducting strip 231, and relative two of one of them section of the 3rd conducting strip 233 can be located in different two sections of the first conducting strip 231.
Because the first conducting strip 231, second conducting strip 232 and the 3rd conducting strip 233 have different length, thus the first conducting strip 231 around the number of turns of magnetic conduction core 21, the second conducting strip 232 around the number of turns of magnetic conduction core 21 and the 3rd conducting strip 233 different around the number of turns of magnetic conduction core 21.In other embodiment, the first conducting strip 231, second conducting strip 232 and the 3rd conducting strip 233 also can have identical or close length, or wherein the two can have identical or close length.Therefore the identical or close length person of tool in the first conducting strip 231, second conducting strip 232 and the 3rd conducting strip 233, in also can be identical on demand around number of turns during magnetic conduction core 21.In the present embodiment, the first conducting strip 231 is ten circles around the number of total coils of magnetic conduction core 21, and the second conducting strip 232 encloses around the number of total coils two of magnetic conduction core 21, and the 3rd conducting strip 233 encloses around the number of total coils three of magnetic conduction core 21, but is not limited thereto.User can adjust the length of the first conducting strip 231, second conducting strip 232 and the 3rd conducting strip 233 according to required number of turns ratio.
In detail, in the present embodiment as shown in FIG. 6 and 7, electric-conductor 23 can be divided into five sections.The part of first paragraph P1 only containing the first conducting strip 231.Second segment P2 contains the part of the second conducting strip 232 and the first conducting strip 231 overlap.The part of 3rd section of P3 also only containing the first conducting strip 231.4th section of P4 contains the part of the 3rd conducting strip 233 and the first conducting strip 231 overlap.The part of 5th section of P5 also only containing the first conducting strip 231.
The first paragraph P1 of electric-conductor 23 first can be wound around magnetic conduction core 21 2 circle, and makes the first conducting strip 231 energy first around magnetic conduction core 21 2 circle.Then, the second segment P2 of electric-conductor 23 can be wound around magnetic conduction core 21 2 circle.Now, the second conducting strip 232 and the first conducting strip 231 are alternately around magnetic conduction core 21.That is, the second conducting strip 232 can first enclose around magnetic conduction core 21 1, and the first conducting strip 231 encloses around magnetic conduction core 21 1 again, and the second conducting strip 232 encloses around magnetic conduction core 21 1 again, and the first conducting strip 231 then encloses around magnetic conduction core 21 1 again.Following again, the 3rd section of P3 of electric-conductor 23 can be wound around magnetic conduction core 21 2 circle again, and makes the first conducting strip 231 again around magnetic conduction core 21 2 circle.
Then, the 4th section of P4 of electric-conductor 23 can be wound around magnetic conduction core 21 3 circle.Now, the 3rd conducting strip 233 and the first conducting strip 231 are alternately around magnetic conduction core 21.Namely, 3rd conducting strip 232 can first enclose around magnetic conduction core 21 1, first conducting strip 231 encloses around magnetic conduction core 21 1 again, make again the 3rd conducting strip 233 around magnetic conduction core 21 1 circle, make the first conducting strip 231 around magnetic conduction core 21 1 circle again, 3rd conducting strip 233 encloses around magnetic conduction core 21 1 again, and the first conducting strip 231 then encloses around magnetic conduction core 21 1 again.Afterwards, the 5th section of P5 of electric-conductor 23 can be wound around magnetic conduction core 21 1 circle again, and makes the first conducting strip 231 again around magnetic conduction core 21 1 circle.
In the present embodiment, from the distribution of the outside electric-conductor 23 of magnetic conduction core 21, be the first conducting strip 231 of two circles, second conducting strip 232 of one circle, first conducting strip 231 of the second conducting strip 232, three circle of the first conducting strip 231, circle of one circle, 3rd conducting strip 233 of one circle, first conducting strip 231 of the 3rd conducting strip 233, circle of the first conducting strip 231, circle of one circle, 3rd conducting strip 233 of one circle, and the first conducting strip 231 of two circles.
Therefore, when electric-conductor 23 is wound around magnetic conduction core 21, the second conducting strip 232 and the 3rd conducting strip 233 crisscross the inside of the number of turns that the first conducting strip 231 causes.By this, the staggered degree of the first conducting strip 231 and the second conducting strip 232 can be promoted, reduce the leakage inductance of the first conducting strip 231 and the second conducting strip 232, and the degree of coupling both promoting.And, the staggered degree of the first conducting strip 231 and the 3rd conducting strip 233 can also be promoted, reduce the leakage inductance of the first conducting strip 231 and the 3rd conducting strip 233, and the degree of coupling both promoting.
In the present embodiment, the number of turns due to the first conducting strip 231 is five times of the number of turns of the second conducting strip 232, therefore the voltage at the two ends of the first conducting strip 231 is about five times of the voltage at the two ends of the second conducting strip 232.The number of turns due to the first conducting strip 231 is three and 1/3rd times of the number of turns of the 3rd conducting strip 233, therefore the voltage at the two ends of the first conducting strip 231 is about three and 1/3rd times of the voltage at the two ends of the 3rd conducting strip 233.
When user will use the transformer 2 shown in Fig. 7, if will from high voltage drop to low-voltage, then can from the two ends high input voltage of more the first conducting strip 231 of the number of turns.Again according to the size of required low-voltage, can switch from less the second conducting strip 232 of the number of turns or the 3rd conducting strip 233 and select and obtain low-voltage.Wherein, because the number of turns of the 3rd conducting strip 233 is many compared with the number of turns of the second conducting strip 232, therefore the voltage that the voltage that the two ends of the 3rd conducting strip 233 obtain can obtain than the two ends of the second conducting strip 232 is high.If high voltage will be risen to from low-voltage, then input low-voltage from less the second conducting strip 232 of the number of turns or the 3rd conducting strip 233, just can obtain high voltage from the two ends of more the first conducting strip 231 of the number of turns.Because the number of turns of the 3rd conducting strip 233 is many compared with the number of turns of the second conducting strip 232, therefore input identical voltage from the two ends of the 3rd conducting strip 233 or the two ends of the second conducting strip 232, the voltage that the voltage that the former obtains from the two ends of the first conducting strip 231 can obtain from the two ends of the first conducting strip 231 lower than the latter.

Please refer to Figure 11 and Figure 12, Figure 11 is the exploded side schematic diagram of the transformer 3 according to another embodiment of the present invention, and Figure 12 is the schematic side view of the transformer 3 of Figure 11.As shown in figure 11, similar with the transformer 2 of Fig. 5 and Fig. 6, the transformer 3 of the present embodiment also comprises the isolated sheet 32 of a magnetic conduction core 31, one and an electric-conductor 33.Electric-conductor 33 comprises one first conducting strip 331,1 second conducting strip 332 and one the 3rd conducting strip 333 be electrically insulated each other.The insulation mode of the first conducting strip 331, second conducting strip 332 and the 3rd conducting strip 333, can be similar with the insulation mode shown in the transformer 2 of Fig. 5, therefore no longer repeated.
But in the present embodiment, the length of the first conducting strip 331 is greater than the length of the second conducting strip 332, the length of the second conducting strip 332 is greater than the length of the 3rd conducting strip 333.When electric-conductor 33 is not yet wound around magnetic conduction core 31, the 3rd conducting strip 333 is stacked on the second conducting strip 332, and the second conducting strip 332 is stacked on the first conducting strip 331.Second outer surface 332b of the second conducting strip 332 is towards the first inner surface 331a of the first conducting strip 331.3rd outer surface 333b of the 3rd conducting strip 333 is towards the second inner surface 332a of the second conducting strip 332.Electric-conductor 33 is wound around isolated 32 coated magnetic conduction cores 31 according to the winding direction R of Figure 11.
As shown in figure 12, electric-conductor 33 is wound around magnetic conduction core 21, and makes the first conducting strip 331, second conducting strip 332 and the 3rd conducting strip 333 around magnetic conduction core 31.Electric-conductor 33, in the process being wound around magnetic conduction core 31, can be stacked over the part that electric-conductor 33 self had previously been wound in magnetic conduction core 31.Therefore, the second at least part of conducting strip 332 and the 3rd at least part of conducting strip 333 can be located in different two sections of the first conducting strip 331.
Because the first conducting strip 331, second conducting strip 332 and the 3rd conducting strip 333 have different length, thus the first conducting strip 331 around the number of turns of magnetic conduction core 31, the second conducting strip 332 around the number of turns of magnetic conduction core 31 and the 3rd conducting strip 333 different around the number of turns of magnetic conduction core 31.In the present embodiment, the first conducting strip 331 is six circles around the number of total coils of magnetic conduction core 31, and the second conducting strip 332 encloses around the number of total coils four of magnetic conduction core 31, and the 3rd conducting strip 333 encloses around the number of total coils two of magnetic conduction core 31, but is not limited thereto.User can adjust the length of the first conducting strip 331, second conducting strip 332 and the 3rd conducting strip 333 according to required number of turns ratio.
In detail, in the present embodiment as shown in FIG. 11 and 12, electric-conductor 33 can be divided into five sections.The part of first paragraph P1 only containing the first conducting strip 331.Second segment P2 contains the part of the second conducting strip 332 and the first conducting strip 331 overlap.3rd section of P3 contains the part of the 3rd conducting strip 333, second conducting strip 332 and the first conducting strip 331 overlap.4th section of P4 also contains the part of the second conducting strip 332 and the first conducting strip 331 overlap.The part of 5th section of P5 also only containing the first conducting strip 331.
The first paragraph P1 of electric-conductor 33 first can be wound around magnetic conduction core 31 1 and 1/2nd circles, and makes the first conducting strip 331 first enclose around magnetic conduction core 1/31st 12.Then, the second segment P2 of electric-conductor 33 can be wound around magnetic conduction core 31 1 circle.Now, the second conducting strip 332 and the first conducting strip 331 are alternately around magnetic conduction core 31.That is, the second conducting strip 332 can first enclose around magnetic conduction core 31 1, and the first conducting strip 331 encloses around magnetic conduction core 31 1 again.
Following again, the 3rd section of P3 of electric-conductor 33 can be wound around magnetic conduction core 31 2 circle again.Now, the 3rd conducting strip 333, second conducting strip 332 and the first conducting strip 331 can alternately around magnetic conduction cores 31.Namely, 3rd conducting strip 333 can first enclose around magnetic conduction core 31 1, second conducting strip 332 encloses around magnetic conduction core 31 1 again, make again the first conducting strip 331 around magnetic conduction core 31 1 circle, make the 3rd conducting strip 333 around magnetic conduction core 31 1 circle again, second conducting strip 332 encloses around magnetic conduction core 31 1 again, and the first conducting strip 331 then encloses around magnetic conduction core 31 1 again.
Then, the 4th section of P4 of electric-conductor 33 can be wound around magnetic conduction core 31 1 circle.Now, the second conducting strip 332 and the first conducting strip 331 are alternately around magnetic conduction core 31.That is, the second conducting strip 332 can first enclose around magnetic conduction core 31 1, and the first conducting strip 331 encloses around magnetic conduction core 31 1 again.Afterwards, the 5th section of P5 of electric-conductor 33 can be wound around magnetic conduction core 1/31st 2 again and enclose, and makes the first conducting strip 331 enclose around magnetic conduction core 1/31st 2 again.
In the present embodiment, from the distribution of the outside electric-conductor 33 of magnetic conduction core 31, be one and the first conducting strips 331 of 1/2nd circles, second conducting strip 332 of one circle, second conducting strip 332 of the 3rd conducting strip 333, circle of the first conducting strip 331, circle of one circle, first conducting strip 331 of one circle, first conducting strip 331 of the second conducting strip 332, circle of the 3rd conducting strip 333, circle of one circle, second conducting strip 332 of one circle, and the first conducting strip 331 of one and 1/2nd circles.
Therefore, when electric-conductor 33 is wound around magnetic conduction core 31, the second conducting strip 332 and the 3rd conducting strip 333 crisscross the inside of the number of turns that the first conducting strip 331 causes.By this, the staggered degree of the first conducting strip 331 and the second conducting strip 332 can be promoted, reduce the leakage inductance of the first conducting strip 331 and the second conducting strip 332, and the degree of coupling both promoting.And, the staggered degree of the first conducting strip 331 and the 3rd conducting strip 333 can also be promoted, reduce the leakage inductance of the first conducting strip 331 and the 3rd conducting strip 333, and the degree of coupling both promoting.In addition, the 3rd conducting strip 333 crisscrosses the inside of the number of turns that the second conducting strip 332 causes.By this, the staggered degree of the second conducting strip 332 and the 3rd conducting strip 333 can be promoted, reduce the leakage inductance of the second conducting strip 332 and the 3rd conducting strip 333, and the degree of coupling both promoting.
In the present embodiment, the number of turns due to the first conducting strip 331 is one and 1/2nd times of the number of turns of the second conducting strip 332, therefore the voltage at the two ends of the first conducting strip 331 is about one and 1/2nd times of the voltage at the two ends of the second conducting strip 332.The number of turns due to the first conducting strip 331 is three times of the number of turns of the 3rd conducting strip 333, therefore the voltage at the two ends of the first conducting strip 331 is about three times of the voltage at the two ends of the 3rd conducting strip 333.The number of turns due to the second conducting strip 332 is two times of the number of turns of the 3rd conducting strip 333, therefore the voltage at the two ends of the second conducting strip 332 is about two times of the voltage at the two ends of the 3rd conducting strip 333.
When user will use the transformer 3 shown in Figure 12, if will from high voltage drop to low-voltage, then can from the two ends high input voltage of more the first conducting strip 331 of the number of turns.Again according to the size of required low-voltage, can switch from less the second conducting strip 332 of the number of turns or the 3rd conducting strip 333 and select and obtain low-voltage.Wherein, because the number of turns of the second conducting strip 332 is many compared with the number of turns of the 3rd conducting strip 333, therefore the voltage that the voltage that the two ends of the second conducting strip 332 obtain can obtain than the two ends of the 3rd conducting strip 333 is high.In addition, also from the two ends high input voltage of more the second conducting strip 332 of the number of turns, and low-voltage can be obtained from the 3rd conducting strip 333 that the number of turns is less.
If high voltage will be risen to from low-voltage, then input low-voltage from less the second conducting strip 332 of the number of turns or the 3rd conducting strip 333, just can obtain high voltage from the two ends of more the first conducting strip 331 of the number of turns.Because the number of turns of the second conducting strip 332 is many compared with the number of turns of the 3rd conducting strip 333, therefore input identical voltage from the two ends of the second conducting strip 332 or the two ends of the 3rd conducting strip 333, the voltage that the voltage that the former obtains from the two ends of the first conducting strip 331 can obtain from the two ends of the first conducting strip 331 lower than the latter.In addition, also low-voltage can be inputted from the 3rd conducting strip 333 that the number of turns is less, just high voltage can be obtained from the two ends of more the second conducting strip 332 of the number of turns.

Please refer to Figure 15 and Figure 16, Figure 15 is the exploded side schematic diagram of the transformer 4 according to another embodiment of the present invention, and Figure 16 is the schematic side view of the transformer 4 of Figure 15.As shown in figure 15, similar with the transformer 3 of Figure 11, the transformer 4 of the present embodiment also comprises the isolated sheet 42 of a magnetic conduction core 41, one and an electric-conductor 43.Electric-conductor 43 comprises one first conducting strip 431,1 second conducting strip 432 and one the 3rd conducting strip 433 be electrically insulated each other.The insulation mode of the first conducting strip 431, second conducting strip 432 and the 3rd conducting strip 433, can be similar with the insulation mode shown in the transformer 2 of Fig. 5, therefore no longer repeated.
But in the present embodiment, when electric-conductor 43 is not yet wound around magnetic conduction core 41, the second outer surface 432b of the second conducting strip 432 is towards the first inner surface 431a of the first conducting strip 431.3rd outer surface 433b of the 3rd conducting strip 433 towards the second conducting strip 432 the second inner surface 432a and towards the first inner surface 431a of the first conducting strip 431, therefore a part for the 3rd conducting strip 433 is simultaneously overlapping with the first conducting strip 431 and the second conducting strip 432, another part is only overlapping with the first conducting strip 431.Electric-conductor 43 is wound around isolated 42 coated magnetic conduction cores 41 according to the winding direction R of Figure 15.
As shown in figure 16, electric-conductor 43 is wound around magnetic conduction core 41, and makes the first conducting strip 431, second conducting strip 432 and the 3rd conducting strip 433 around magnetic conduction core 41.Electric-conductor 43, in the process being wound around magnetic conduction core 41, can be stacked over the part that electric-conductor 43 self had previously been wound in magnetic conduction core 41.Therefore, the second at least part of conducting strip 432 and the 3rd at least part of conducting strip 433 can be located in different two sections of the first conducting strip 431.
Because the first conducting strip 431, second conducting strip 432 and the 3rd conducting strip 433 have different length, thus the first conducting strip 431 around the number of turns of magnetic conduction core 41, the second conducting strip 432 around the number of turns of magnetic conduction core 41 and the 3rd conducting strip 433 different around the number of turns of magnetic conduction core 41.In the present embodiment, the first conducting strip 431 is six circles around the number of total coils of magnetic conduction core 41, and the second conducting strip 432 encloses around the number of total coils three of magnetic conduction core 41, and the 3rd conducting strip 433 encloses around the number of total coils two of magnetic conduction core 41, but is not limited thereto.User can adjust the length of the first conducting strip 431, second conducting strip 432 and the 3rd conducting strip 433 according to required number of turns ratio.
In detail, in the present embodiment as shown in Figure 15 and Figure 16, electric-conductor 43 can be divided into five sections.The part of first paragraph P1 only containing the first conducting strip 431.Second segment P2 contains the part of the second conducting strip 432 and the first conducting strip 431 overlap.3rd section of P3 contains the part of the 3rd conducting strip 433, second conducting strip 432 and the first conducting strip 431 overlap.4th section of P4 contains the part of the 3rd conducting strip 433 and the first conducting strip 431 overlap.The part of 5th section of P5 also only containing the first conducting strip 431.
The first paragraph P1 of electric-conductor 43 first can be wound around magnetic conduction core 41 1 and 1/2nd circles, and makes the first conducting strip 431 first enclose around magnetic conduction core 1/41st 12.Then, the second segment P2 of electric-conductor 43 can be wound around magnetic conduction core 41 2 circle.Now, the second conducting strip 432 and the first conducting strip 431 are alternately around magnetic conduction core 41.That is, the second conducting strip 432 can first enclose around magnetic conduction core 41 1, and the first conducting strip 431 encloses around magnetic conduction core 41 1 again, and the second conducting strip 432 encloses around magnetic conduction core 41 1 again, and the first conducting strip 431 then encloses around magnetic conduction core 41 1 again.
Following again, the 3rd section of P3 of electric-conductor 43 can be wound around magnetic conduction core 41 1 circle again.Now, the 3rd conducting strip 433, second conducting strip 432 and the first conducting strip 431 can alternately around magnetic conduction cores 41.That is, the 3rd conducting strip 433 can first enclose around magnetic conduction core 41 1, and the second conducting strip 432 encloses around magnetic conduction core 41 1 again, makes again the first conducting strip 431 around magnetic conduction core 41 1 circle.
Then, the 4th section of P4 of electric-conductor 43 can be wound around magnetic conduction core 41 1 circle.Now, the 3rd conducting strip 433 and the first conducting strip 431 are alternately around magnetic conduction core 41.That is, the 3rd conducting strip 433 can first enclose around magnetic conduction core 41 1, and the first conducting strip 431 encloses around magnetic conduction core 41 1 again.Afterwards, the 5th section of P5 of electric-conductor 43 can be wound around magnetic conduction core 1/41st 2 again and enclose, and makes the first conducting strip 431 enclose around magnetic conduction core 1/41st 2 again.
In the present embodiment, from the distribution of the outside electric-conductor 43 of magnetic conduction core 41, be one and the second conducting strip 432 that the first conducting strips 431, of 1/2nd circles enclose, first conducting strip 431 of one circle, 3rd conducting strip 433 of the first conducting strip 431, circle of the second conducting strip 432, circle of one circle, second conducting strip 432 of one circle, 3rd conducting strip 433 of the first conducting strip 431, circle of one circle, and the first conducting strip 431 of one and 1/2nd circles.
Therefore, when electric-conductor 43 is wound around magnetic conduction core 41, the second conducting strip 432 and the 3rd conducting strip 433 crisscross the inside of the number of turns that the first conducting strip 431 causes.By this, the staggered degree of the first conducting strip 431 and the second conducting strip 432 can be promoted, reduce the leakage inductance of the first conducting strip 431 and the second conducting strip 432, and the degree of coupling both promoting.And, the staggered degree of the first conducting strip 431 and the 3rd conducting strip 433 can also be promoted, reduce the leakage inductance of the first conducting strip 431 and the 3rd conducting strip 433, and the degree of coupling both promoting.
In the present embodiment, the number of turns due to the first conducting strip 431 is two times of the number of turns of the second conducting strip 432, therefore the voltage at the two ends of the first conducting strip 431 is about two times of the voltage at the two ends of the second conducting strip 432.The number of turns due to the first conducting strip 431 is three times of the number of turns of the 3rd conducting strip 433, therefore the voltage at the two ends of the first conducting strip 431 is about three times of the voltage at the two ends of the 3rd conducting strip 433.The number of turns due to the second conducting strip 432 is one and 1/2nd times of the number of turns of the 3rd conducting strip 433, therefore the voltage at the two ends of the second conducting strip 432 is about one and 1/2nd times of the voltage at the two ends of the 3rd conducting strip 433.
When user will use the transformer 4 shown in Figure 16, if will from high voltage drop to low-voltage, then can from the two ends high input voltage of more the first conducting strip 431 of the number of turns.Again according to the size of required low-voltage, can switch from less the second conducting strip 432 of the number of turns or the 3rd conducting strip 433 and select and obtain low-voltage.Wherein, because the number of turns of the second conducting strip 432 is many compared with the number of turns of the 3rd conducting strip 433, therefore the voltage that the voltage that the two ends of the second conducting strip 432 obtain can obtain than the two ends of the 3rd conducting strip 433 is high.
If high voltage will be risen to from low-voltage, then input low-voltage from less the second conducting strip 432 of the number of turns or the 3rd conducting strip 433, just can obtain high voltage from the two ends of more the first conducting strip 431 of the number of turns.Because the number of turns of the second conducting strip 432 is many compared with the number of turns of the 3rd conducting strip 433, therefore input identical voltage from the two ends of the second conducting strip 432 or the two ends of the 3rd conducting strip 433, the voltage that the voltage that the former obtains from the two ends of the first conducting strip 431 can obtain from the two ends of the first conducting strip 431 lower than the latter.
