Description
Technical field
The present invention relates to a kind of inducer, more particularly to a kind of high-power annular inductor device, the high-power annular inductor device
In for power electronics RF power transformation system, belong to inductor structure design field.
Background technology
With the development of industrial technology, inductor in high frequency requires high-power, small size, especially ring-type inductive device, due to
Limited by powder magnet ring process conditions, the magnet ring window (internal diameter) used by inductor in high frequency is typically small, is available for the sky of coiling
Between it is not enough, govern the lifting of inductor in high frequency power density.
In prior art, manufacture high-power high-frequency inducer can only with after rope-lay strand or cable parallel connection in magnet ring around
System, the wire for being distributed in magnet ring circumferencial direction and radial direction is all very big, occupies larger magnet ring window (internal diameter) space, causes magnetic
The coil turn of coiling is few on ring, it is impossible to meet the needs of inducer performance indications.
Because the magnet ring used by inductor in high frequency is mostly the annulus of closing, coil is that the flexible wire of apparatus is (such as more
Stock twisted wire, small section lead are in parallel) form through the coiling of magnet ring center, the rigid conductive such as copper coin material is because magnetic cannot be passed through
Ring, it is impossible to carry out coiling with prior art.And the rigid conductive such as copper coin material can form the high-frequency electrical of high power density
Sensor, therefore, the rigid conductive such as design copper coin material has good economic valency as the high-power high-frequency inducer of coil
Value and technological value.
The content of the invention
The present invention is intended to provide high-power annular inductor in high frequency, mainly includes：Toroidal core 1 and coil 2, the ring of pitch of the laps 2
It is wound on magnet ring 1, the coil 2 is connected by the head and the tail of connection parts 22 by breach endless member 21 and is formed.The breach ring-type
Part 21 has head end 211 and tail end 212, and the tail end 212 is located in magnet ring window, and head end 211 is located at outside magnet ring.So
Structure design enable the coil of high-power annular inductor in high frequency to use the rigid conductive material manufacture such as copper coin, with obtain compared with
Big conductive section, and take less magnet ring window (internal diameter) space.
The wire coiling that the coil (2) can also be changed by cross sectional shape and sectional area is formed, conductor cross-section change
Rule is diminished positioned at magnet ring window direction conductor cross-section, and the method for realization copper conductor is drawn or can extrude copper conductor
When change cross sectional shape and sectional area.This wire can by hand wear into coil when not very big.Wire can when big
To pierce coil with machine.

Specific embodiment
By the materials processing of the rigid conductive such as copper coin into breach endless member 21 and connection parts 22, preferably by breach annulus
Part 21 is processed into U-shaped as shown in Figure 3, preferably connection parts 22 is processed into into the reverse-s shape shown in Fig. 4, by U-shaped member 21 along magnetic
Ring is axially inserted into, and wherein U-shaped member tail end 212 is located in magnet ring window, and U-shaped member head end 211 is located at outside magnet ring, then with anti-
S-shaped part is connected U-shaped member head and the tail, with regard to connecting mode, can with using butt welding mode as depicted in figs. 1 and 2,
Overlap joint welding manner as shown in Figure 5 can be adopted, can also be coupled using bolt joint group part 25 as shown in Figure 6, again finally
Coil input end 23 and outfan 24 are soldered on a U-shaped tail end of free time and reverse-s shape connection parts, such as Fig. 1 is just constituted
Shown inducer.
Further, in processing coil 2, it is possible to reduce the sectional area of U-shaped member tail end 212, while increasing U-shaped member
The sectional area at remaining position, whole U-shaped keep all-in resistance constant and make the sectional area of U-shaped member tail end 212 less than U-shaped member its
The sectional area of remaining part position, so that the magnet ring window that coil takes is less, obtains more to obtain on the magnet ring of same specification
Coil turn.
By experimental verification, the sectional area of U-shaped member tail end 212 is designed as the sectional area at remaining position of U-shaped member
3/4ths, while realizing that whole U-shaped keeps all-in resistance constant, filling of the wire in magnet ring window when whole inductance
The effect that the caloric value and the number of turn of device can be optimal.
Further, as shown in fig. 7, can be by the materials processing of the rigid conductive such as copper coin into breach endless member 21 and connection
Part 22 is applied to high-power annular high frequency transformer.When high-power annular high frequency transformer is manufactured, as above-mentioned high-power
Annular inductor in high frequency is the same, the breach of the breach endless member 21 of primary coil is placed in one end of magnet ring 1, and secondary coil lacks
The breach of mouth endless member 21 " is placed in the other end of magnet ring 1, breach endless member 21 and the head and the tail of connection parts 22 of primary coil
The connecting mode of the breach endless member 21 of connecting mode and secondary coil " and connection parts 22 " head and the tail adopts butt welding
Couple with overlap joint welding or bolt assembly 25；
Further, when high-power annular high frequency transformer is manufactured, breach endless member 21 and the secondary of primary coil
The breach endless member 21 of coil " can also be adopted first around primary coil further around secondary wire with employing folder separately around mode
The independent segmented mode of circle.
