Abstract

The utility model discloses a novel transformer, which comprises a magnet bracket, wherein the magnet bracket is provided with a plurality of magnetic circuits which are formed by magnetic cores, the magnetic circuits are respectively and alternatively provided with a primary winding and a secondary winding, and the quantity of the magnetic circuits which are surrounded by the primary winding is not equal to that of the magnetic circuits which hare surrounded by the secondary winding. The novel transformer overcomes the weaknesses of the prior art, has simple structure, can produce adequate inductance to substitute the external inductance, and can effectively reduce the cost.

Description

A kind of novel transformer
[technical field]
The utility model relates to a kind of novel transformer.
[background technology]
In the application of resonant power, usually need transformer is used in combination with inductance, traditional way is at inductance of the outside of transformer series connection.This way has increased the cost of realizing resonant power and has taken a large amount of spaces, and resonant power needs between the primary inductance of resonant inductance and transformer a fixing ratio is arranged, and adopts the method for outside series inductance, is difficult to draw ratio accurately.The leakage inductance of transformer is that the magnetic line of force that coil produces can not all pass through secondary coil, and the inductance that therefore produces leakage field is called leakage inductance, it just as one independently inductance seal in circuit.The someone adopts the magnetic material of Different Rule to produce the inductance that leakage inductance replaces outside series connection for this reason, but this technology is relatively complicated.
[utility model content]
The utility model purpose is to have overcome deficiency of the prior art, provides a kind of simple in structure, can produce enough leakage inductances and replace external inductance, thus the novel transformer that effectively reduces cost.
The utility model is achieved through the following technical solutions:
A kind of novel transformer, comprise a magnet frame, on described magnet frame, be provided with and a plurality ofly form magnetic circuit by magnetic core, staggered successively respectively elementary winding and the secondary winding of being wound with on described magnetic circuit, the magnetic circuit number that magnetic circuit number that described elementary winding surrounds and described secondary winding surround is unequal.
Aforesaid a kind of novel transformer wherein is provided with five and forms magnetic circuit by magnetic core on described magnet frame, described elementary winding technique is on the odd number magnetic circuit, and described secondary winding is wound on the even number magnetic circuit.
Aforesaid a kind of novel transformer wherein is provided with five and forms magnetic circuit by magnetic core on described magnet frame, described secondary winding is wound on the odd number magnetic circuit, and described elementary winding technique is on the even number magnetic circuit.
Aforesaid a kind of novel transformer, wherein said magnetic core are the U-shaped magnetic core.
Aforesaid a kind of novel transformer, wherein said magnetic core are the CD iron core.
Aforesaid a kind of novel transformer, wherein said magnetic core are circular stem stem magnetic core.
Aforesaid a kind of novel transformer, wherein said magnetic core is the silicon steel sheet magnetic core of band newel.
Compared with prior art, the utility model has following advantage:
Interlocking successively respectively on a plurality of magnetic circuits in the utility model is wound with elementary winding and secondary winding, and has only a winding on each magnetic circuit; Because the magnetic circuit number that magnetic circuit number that elementary winding surrounds and secondary winding surround is unequal, thereby produce leakage inductance, it is simple in structure, and coiling is convenient; By calculating the magnetic field that elementary winding and secondary winding are coupled fully, the no-load voltage ratio of calculating transformer is according to this regulated the coil number of elementary winding or secondary winding then, just can realize that the leakage inductance of being scheduled to is few greatly, replace external inductance thereby become an equivalent resonant inductance, saved production cost.
[description of drawings]
Fig. 1 is the schematic diagram of first kind of execution mode of the utility model;
Fig. 2 is the schematic diagram of second kind of execution mode of the utility model.
[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
A kind of novel transformer as shown in Figure 1, comprise a magnet frame 1, on described magnet frame 1, be provided with and a plurality ofly form magnetic circuit by magnetic core 2, staggered successively respectively elementary winding 3 and the secondary winding 4 of being wound with on described magnetic circuit, wherein on each magnetic circuit, has only a winding, the magnetic circuit number that magnetic circuit number that described elementary winding 3 surrounds and described secondary winding 4 surround is unequal, and wherein said elementary winding 3 is connected in parallel, and described secondary winding 4 is connected in parallel.
Be provided with five in the utility model and form magnetic circuit by magnetic core 2 on described magnet frame 1, described elementary winding 3 is wound on the odd number magnetic circuit, and described secondary winding 4 is wound on the even number magnetic circuit.
Another kind of execution mode of the present utility model is provided with five and forms magnetic circuit by magnetic core 2 as shown in Figure 2 on described magnet frame 1, described secondary winding 4 is wound on the odd number magnetic circuit, and described elementary winding 3 is wound on the even number magnetic circuit.
Magnetic core 2 described in the utility model can be a kind of in the silicon steel sheet magnetic core of U-shaped magnetic core, CD iron core, circular stem stem magnetic core or band newel.
In the needed transformer of general resonant power, inductive proportions between resonant inductance and the primary winding should be fixed as between 1: 4~1: 7, the utility model surrounds different magnetic circuit numbers by design of transformer being become elementary winding and secondary winding, and the leakage inductance that produces can equivalence be a resonant inductance, because what influence leakage inductance surrounds different magnetic circuit numbers and winding parameter (such as coil turn because of factor mainly comprises elementary winding and secondary winding, magnetic gap is few greatly), and these factors all are to be easy to control realize, and the ratio between consequent equivalent resonant inductance and the primary winding is also relatively stable, by calculating the magnetic field that elementary winding and secondary winding are coupled fully, the no-load voltage ratio of calculating transformer according to this, regulate the coil number of elementary winding or secondary winding then, just can realize that the leakage inductance of being scheduled to is few greatly, thereby become an equivalent resonant inductance and replace external inductance, satisfy inductive proportions between resonant inductance and the primary winding and be fixed as requirement between 1: 4~1: 7, the utility model transformer device structure is simple, has saved production cost.
