Five posts of three-phase transformer 2 volume is unshakable in one's determination 23, and the volume core unit through the different annular of combined openings size constitutes in the front view shape in the form of a substantially rectangular, and said five posts volume unshakable in one's determination 23 comprises: an outer core unit 231, opening size maximum; Two middle core unit 232 be arranged to contact with the interior lateral circle surface of outer core unit 231, and two middle core unit 232 are in contact with one another; And four little core unit 233a, 233a, 233b, 233b, be arranged to contact, and two little core unit 233a, 233b are in contact with one another with the interior lateral circle surface of middle core unit 232.
The shape of two middle core unit 232 is identical, and its thickness is identical with the thickness of said outer core unit 231.In addition, be arranged in four little core unit about the thickness of little core unit 233a in the outside identical with the thickness that outer core unit 231 reaches middle core unit 232.On the other hand, the thickness that is arranged on the little core unit 233b of center side in the little core unit be arranged on the outside little core unit 233a thickness 1/2nd.Five post 23a～23e of five posts of structure volume unshakable in one's determination 23 arrange about the edge in front view as stated; Among five post 23a～23e; The post 23b of post 23a and the right ends of central authorities, the sectional area of 23c are identical, the post 23d adjacent, the sectional area of 23e with the both sides of the post 23a of central authorities be central post 23a and right ends post 23b, 23c sectional area 1/2nd.
In addition; In the five posts volume unshakable in one's determination 23 of structure as stated; The post 23b of post 23a and the right ends of central authorities, 23c constitute the wound core portion that is wound with primary winding 21u, 21v, 21w and secondary coil 22u, 22v, 22w, become the loop core part that constitutes single-phase high frequency magnetic flux magnetic circuit with adjacent post 23d, the 23e in both sides of the post 23a of central authorities.That is the sectional area that, constitutes the loop core part of single-phase high frequency magnetic flux magnetic circuit be wound with primary winding 21u, 21v, 21w and secondary coil 22u, 22v, 22w wound core portion sectional area 1/2nd.According to described five posts volume unshakable in one's determination 23; Single-phase high frequency magnetic flux magnetic circuit is arranged between the post 23a～23c that is wound with primary winding 21u, 21v, 21w, secondary coil 22u, 22v, 22w, can make the circulation of the single-phase high frequency magnetic flux of each post 23a～23c generation become easy.
At this, in the past single-phase 9 frequencys multiplication are taken place to be illustrated among Fig. 9 with the primary winding polar plot of single-phase transformer, in the past the single-phase 9 frequencys multiplication generation winding diagram with single-phase transformer is illustrated among Figure 10.As shown in the figure; As single-phase 9 overtones bands (n is 3 o'clock) generating means in the past; The primary winding of 9 single-phase transformers is implemented the phse conversion winding that makes phase place stagger 40 degree successively and carries out Y to connect; And the phase place of secondary coil 40 degree that stagger successively are connected in series, take out the single-phase voltage of 9 overtones bands from the two ends of the secondary coil that is connected in series.In addition, for the high frequency generating apparatus of this execution mode, primary winding polar plot as shown in Figure 9 is identical.
On the other hand, the winding diagram that the use high frequency generating apparatus of this execution mode is produced under the single-phase 9 overtones band situation is illustrated among Figure 11.Said high frequency generating apparatus comprises: as first three-phase transformer 2A that is wound with primary winding R phase/S phase/T phase of benchmark; Adopted second the three-phase transformer 2B that has the primary winding of 40 degree phase differences with respect to said first three-phase transformer 2A; And adopted the 3rd the three-phase transformer 2C of primary winding that has 40 degree phase differences with respect to said second three-phase transformer 2B.And, first～primary winding of the 3rd three-phase transformer 2A～2C is connected in series, and first～the 3rd three-phase transformer 2A～2C carry out Y as a whole and connect.In addition, first～secondary coil of the 3rd each phase of three-phase transformer 2A～2C is connected in series with stagger the successively mode of 40 degree of phase place.Like this, export the single-phase voltage (with reference to Figure 12) of single-phase 9 overtones bands from the two ends of the secondary coil that is connected in series.
The characteristic of table 2 expression three-phase input voltage/single-phase 9 frequency multiplication output voltages, Figure 13 representes the performance plot of output voltage/output voltage calculated value-magnetic flux density unshakable in one's determination.Wherein, the output voltage calculated value is the voltage that calculates according to coil ratio.3n frequency multiplication voltage is about 30% with respect to the turn ratio calculated value of input voltage because output winding for be connected in series and frequency be 3n doubly, so the magnetic flux on the 3n overtones band magnetic flux path is to be wound with about 30% of magnetic flux on the post of coil.Promptly; 3n overtones band magnetic flux path is on two posts; Therefore the magnetic flux on the average post is compared with other three posts and is about 15%, if consider frequency reach 3n doubly and iron loss increase, the sectional area that can know the post that is not wound with coil should be the post that is wound with coil sectional area 50%.
According to the high frequency generating apparatus of this execution mode of structure as stated; Three-phase transformer 2 is that five posts volume is unshakable in one's determination; Last primary winding 21u, 21v, 21w, secondary coil 22u, 22v, the 22w of being wound with of three post 23a～23c wherein; Remaining two post 23d, 23e constitute single-phase high frequency magnetic flux magnetic circuit; The phase place that each post 23a～23c of being wound with primary winding 21u, 21v, 21w, secondary coil 22u, 22v, 22w is produced is identical and to the high frequency magnetic flux that equidirectional flows, and through two remaining post 23d, 23e circulation, thereby can prevent that the high frequency magnetic flux that three-phase transformer 2 produces from reducing.Thus, can make the output capacity (output voltage) of 3n overtones band big with respect to the ratio change of the input capacity (input voltage) of industrial power frequency.In addition; Five posts volume unshakable in one's determination 23 is the annulars that form through the laminal electromagnetic steel plate of continuous reeling; Therefore can reduce the magnetic resistance in the magnetic circuit of high frequency magnetic flux as much as possible; Thereby the magnetic flux in the time of can preventing the high frequency magnetic flux through each post 23a～23e reduces, and can make output/input than change as much as possible greatly.In addition, owing to can use three-phase transformer 2, therefore compare, can make apparatus structure compact, and can make wiring simple with the situation of in the past three single-phase transformers of use.
In addition, the utility model is not limited to said execution mode, in the scope that does not break away from the utility model technological thought, certainly carries out various distortion.For example; In said execution mode; As concrete example; Single-phase voltage to using three three-phase transformers to export 9 overtones bands is illustrated, and also can use 5 three-phase transformers to export the single-phase voltage of 15 overtones bands, can also use the single-phase voltage than the three-phase transformer output 3n overtones band of said the more odd number platform of number.
In addition, the utility model is not limited to said each execution mode, in the scope that does not break away from the utility model technological thought, certainly carries out various distortion.
