Description
Technical field
The present invention relates to a kind of transformator with the winding drafting department (Coil Pattern) containing flat section configuration
(Trans(former))。
Background technology
In the past, it is known that a kind of around the cylindrical shape portion 92 of iron core (Core) 90, by the first spiral 101 and volume Two
Line 102 is via layer (Layer) paper 105 or plate-like portion so as to the transformator being wound is (with reference to Japanese Unexamined Patent Publication 2012-164928
Number).In addition, Fig. 4 is the cross-sectional view of the transformator of the past technology, in the first spiral 101 as shown in Figure 4 and the second spiral 102
Each by insulating component coat.
Make using the conventional transformator of spiral 101,102 as described so under higher frequency (such as 70kHz)
In the case of carrying out action, due to Kelvin effect (Skin Effect), electric current flows only through the surface of spiral 101,102.Therefore,
In spiral 101, the area of section that electric current flows through in 102 diminishes, and further results in resistance increase.
Further, since electric current is flow through to same direction between the first spiral 101 and between the second spiral 102, therefore
In form as described in Figure 4, due to so-called kindred effect, cause to flow through between the electric current in the first spiral 101 or flow
It is mutually exclusive between the electric current crossed in the second spiral 102, each spiral 101 is flow through, the electric current in 102 is in the position being separated from each other
Flow through.When each spiral 101 is flow through, when the electric current in 102 is flow through in the position being separated from each other like this, in spiral 101,102
The area of section that middle electric current flows through diminishes, and further results in resistance increase.
In the form wound by the first spirals 101 or the second spiral 102 more than three row as shown in Figure 4, it is subject to
The impact of both Kelvin effect and kindred effect, electric current become to be difficult to flow through the first spiral 101 or volume Two positioned at inner side
Line 102, causes resistance increase a lot.More specifically, in the form shown in Fig. 4, the in the first spirals 101 of three row
First spiral 101 of two row and not second positioned at the first spiral 101 of upper and lower end parts and in the second spiral 102 of three row
Row the second spiral 102 and not positioned at upper and lower end parts the second spiral 102 in, electric current becomes to be difficult to flow through, and causes resistance to increase
A lot.
Once resistance increase as mentioned above, causes the temperature for producing spiral 101,102 to rise, resistance further becomes big evil
Property circulation.
In addition, in recent years, the miniaturization of transformator always in being sought, in the past technology, as thickness is 50um
The presence of the layer paper 105 of left and right, area of section are circular spiral 101, and the feelings such as useless space occurs in the space between 102
Condition, there are problems that being difficult to as the size of diminution transformator.
In addition, when spiral 101,102 completes winding, by ensuing spiral 101, before 102 are wound, needing
Arrange in the terminal part of the spiral 101,102 for completing to wind and terminate implant (End Filler), but be used for like this arranging knot
The space of beam implant is useless in itself.In addition, in spiral 101,102 is before m rotations (" m " is integer) windings are completed
At the end of way, rotate to arrange on the position wound before completing in m and terminate implant, afterwards to ensuing spiral 101,102
Be wound, but ought like this m rotate winding complete before position on arrange terminate implant and to ensuing volume
When line 101,102 is wound, there is the probability that ensuing spiral 101,102 crumbles.
As the past technology, except above-mentioned Japanese Unexamined Patent Publication 2012-164928, it is also known that Japanese Unexamined Patent Publication 7-130554
Publication.In the Japanese Unexamined Patent Publication 7-130554 publication, it is striped to disclose elongated strip conductor layer is printed
(Stripe) shape so as to constitute the first conductivity type thin-film (Film) body, and by thick strip conductor layer printing for striated so as to
The method of the second conductive thin film body superposition for constituting.
However, being bar by the printing of strip conductor layer as disclosed in Japanese Unexamined Patent Publication 7-130554 publication
In the case of stricture of vagina shape, the width (length in the direction perpendicular with coiling direction) of strip conductor layer diminishes.Therefore, each strip
The area of section of conductor layer diminishes, and causes the impact caused by above-mentioned Kelvin effect to become big, causes the area of section that electric current flows through
Diminish.
In addition, in the form disclosed in Japanese Unexamined Patent Publication 7-130554 publication, elongated strip conductor layer exists each other
Adjacent on same plane, thick strip conductor layer is adjacent at grade each other.It is additionally, since in length adjacent to each other
In strip conductor layer, electric current flows through in the same direction, therefore due to by above-mentioned kindred effect, flowing through in elongated strip conductor layer
Electric current between and flow through in thick strip conductor layer electric current between it is mutually exclusive, cause the electricity in each strip conductor layer
The area of section that stream flows through diminishes.
Therefore, as disclosed in Japanese Unexamined Patent Publication 7-130554 publication it is bar by the printing of strip conductor layer
In the form of stricture of vagina shape, affected by both Kelvin effect and kindred effect, cause resistance to become big.And, when resistance like this
When becoming big, as described above, causing the temperature for producing strip conductor layer to rise, resistance further becomes big vicious cycle.
