Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "comprising" and "having," and any variations thereof, as referred to in the embodiments of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In power electronic converters, the volume fraction of the magnetic components is typically over 30%, and the loss fraction can reach 50%, which is one of the important factors affecting the efficiency and power density of the converter. Wherein, inductance and transformer are the main part of magnetic element, and both can carry out the magnetism integration, can reduce the volume of magnetic element by a wide margin, raise the efficiency. The leakage inductance can be used as an energy storage inductance, and can completely replace an external inductance when the leakage inductance is large enough, so that high magnetic integration is realized.
At present, one technical route is to separate primary and secondary windings and increase the leakage inductance by increasing the winding spacing; another technical route is to keep the windings staggered to some extent, and increase the leakage inductance by adding extra magnetic columns, but both technical routes result in severe leakage flux in the air outside the magnetic core.
Based on this, the integrated magnetic element device and the converter provided by the embodiment of the application alleviate the technical problem that the diffusion leakage flux on the outer side of the magnetic core passes through a large amount.
For the understanding of the present embodiment, a detailed description will be given of an integrated magnetic element device disclosed in the embodiments of the present application.
Fig. 1 is a schematic structural diagram of an integrated magnetic component device according to an embodiment of the present application. As shown in fig. 1, the apparatus includes: the transformer comprises a primary winding and a secondary winding, wherein the primary winding and the secondary winding are arranged on the magnetic core in a surrounding mode, and the primary winding and the secondary winding are used for providing windings for the transformer and the inductor. The coupling degree of primary and secondary windings (such as the window outer winding 1 and the window outer winding 2) at the outer side of the window of the magnetic core is higher than the preset coupling degree, and the coupling degree of the primary and secondary windings at the inner side of the window of the magnetic core is lower than the preset coupling degree.
It should be noted that the primary and secondary windings include a primary winding and a secondary winding, which serve as both a transformer winding and an inductor winding. The preset coupling degree is a target coupling degree which can be preset in advance according to the inductance value required by the current converter.
For example, in contrast, as shown in fig. 2, a cross-sectional view of an integrated magnetic component with uniform coupling of the inner and outer windings of the core window is shown. As shown in fig. 1, is an integrated magnetic component with inconsistent winding coupling inside and outside the window of the core. Because the primary and secondary windings (such as the window outer winding 1 and the window outer winding 2) at the outer side of the window are high in coupling degree, the magnetic leakage is favorably reduced, and the alternating current coefficient of the windings is favorably improved; the primary and secondary windings at the inner side of the window are low in coupling degree, and larger leakage inductance is constructed beneficially.
Therefore, through constructing the integrated magnetic structure with inconsistent coupling degrees of the primary and secondary windings at the outer side in the window of the magnetic core, the coupling degree of the primary and secondary windings at the outer side of the window is higher than the preset coupling degree, and the coupling degree of the primary and secondary windings at the inner side of the window is lower than the preset coupling degree, so that the magnetic flux leakage from the magnetic element to the outer side can be reduced, the loss is reduced, and the overall efficiency and the power density are improved.
Embodiments of the invention are further described below.
In some embodiments, varying the degree of interleaving of the windings may vary the degree of coupling of the windings, while providing different degrees of interleaving at the inner and outer sides of the window of the core. Based on this, the degree of staggering of the primary and secondary windings around the magnetic core is greater than the preset degree of staggering, so that the magnetic core externally diffused leakage flux is reduced.
For example, as shown in fig. 1, the primary and secondary windings are sufficiently wound on the magnetic core in a staggered manner, so that a high degree of coupling of the windings at the outer side of the window (e.g., the window outer winding 1 and the window outer winding 2) is realized. Therefore, the degree of interleaving of the primary winding and the secondary winding is changed, the coupling degree of the inner winding and the outer winding of the window is inconsistent, and the influence of the magnetic core on the external diffusion leakage magnetic flux can be reduced due to the high coupling degree of the winding at the outer side of the window.
In some embodiments, varying the degree of interleaving of the windings may vary the degree of coupling of the windings such that there is a different degree of interleaving at the inside and outside of the window of the core. Based on this, the degree of staggering of the primary and secondary windings at the inner side of the window of the magnetic core around the magnetic core is smaller than the preset degree of staggering, so that the leakage flux at the inner side of the window of the magnetic core is increased.
For example, as shown in fig. 1, the primary and secondary windings are insufficiently cross-wound around the core, achieving a low degree of coupling of the windings at the inner side of the window. Because the coupling degree of the primary and secondary windings at the inner side of the window is low, large leakage inductance can be constructed, and the leakage flux at the inner side of the window of the magnetic core is increased. Therefore, the degree of staggering of the primary winding and the secondary winding at the inner side of the window is changed, the leakage flux at the inner side of the window of the magnetic core is increased, and the overall efficiency of the magnetic element is improved.
Based on this, the degree of the setting of the interleaving is determined according to the parameters of the primary and secondary windings and the magnetic core. Illustratively, the corresponding arrangement staggering degree at the outer side of the window of the magnetic core and the corresponding arrangement staggering degree at the inner side of the window of the magnetic core are determined according to the winding length of the primary and secondary windings and the inner and outer side leakage flux value of the magnetic core.
The winding length of the primary and secondary windings and the value of the leakage flux inside and outside the magnetic core affect the degree of interleaving of the primary and secondary windings. For example, as shown in fig. 3, the greater the number of turns of the wire, the longer the length of the wire, and the tradeoff is to optimize the degree of interleaving of the primary and secondary windings inside and outside the core window, which can affect the bulk and overall efficiency of the magnetic element.
Therefore, the interleaving degree of the primary and secondary windings is determined by the winding length of the primary and secondary windings and the inner and outer side leakage flux values of the magnetic core, the whole volume of the magnetic element can be effectively reduced, and the whole power density is improved.
In some embodiments, the leakage flux is increased by additionally inserting a magnetic pillar. As an example, between the primary and secondary windings at the inside of the window of the magnetic core, an additional magnetic pole is interposed to increase the leakage flux inside the window of the magnetic core.
For example, as shown in fig. 3 and 4, a magnetic pole is additionally inserted between the primary and secondary windings at the inner side of the window. Therefore, the extra leakage magnetic path is constructed by additionally inserting the magnetic pillar, so that more leakage inductance can be constructed in a limited volume, and the leakage magnetic flux inside the window is increased.
Based on the position and the number of the additional magnetic columns, the position and the number of the additional magnetic columns are determined according to the parameters of the primary and secondary windings and the magnetic core. Illustratively, the position and the number of the additional magnetic columns at the inner side of the window of the magnetic core are determined according to the winding length of the primary and secondary windings and the inner and outer side leakage flux values of the magnetic core.
It should be noted that the winding length of the primary and secondary windings and the value of the leakage flux inside and outside the magnetic core affect the position and number of the extra magnetic poles. For example, as shown in fig. 3, the greater the number of additional magnetic pillars, the higher the overall efficiency and power density can be achieved.
Therefore, according to actual needs, confirm the position and the quantity that set up extra magnetic pillar, can effectively reduce the whole volume of magnetic element, improve the reliability of whole circuit.
In some embodiments, the parameters of the core and the additional columns may be adjusted according to the actual application. As an example, the winding form of the primary and secondary windings around the magnetic core and the insertion form of the additional magnetic pole at the inner side of the window of the magnetic core are determined according to the structure of the magnetic core, so as to reduce the winding length of the windings.
For example, as shown in fig. 5, the winding length can be reduced by optimizing the inserted pole form and the winding form of the winding. Therefore, the interleaving degree of the inner and outer windings of the window can be adjusted according to actual requirements, the position, the number and the like of the magnetic columns inserted into the window are changed, the size of leakage inductance can be adjusted, the requirements on overall efficiency and size are met, and the flexibility of actual application is improved.
In some embodiments, the main magnetic circuit of the transformer may be of a particular configuration. As an example, the main magnetic circuit of the transformer is an E-type core structure. The E-core is a core shape used in a general transformer. For example, as shown in fig. 6, the main magnetic path of the transformer has an E-type core structure.
Based on this, can be according to actual need, the coiling form of changing main magnetic circuit and the inserted mode of extra magnetic pole. Illustratively, the winding form of the primary and secondary windings around the main magnetic circuit and the arrangement and insertion form of the additional magnetic pole at the inner side of the window of the main magnetic circuit are determined according to the structure of the E-shaped magnetic core.
The winding mode of the inserted extra magnetic pole and the winding is correspondingly changed, so that the primary and secondary windings (such as the window outer side winding 1 and the window outer side winding 2) on the outer side of the window are well coupled, the primary and secondary windings on the inner side of the window are in a weak coupling structure, and the size of leakage inductance can be adjusted. Thus, the transformer maintains a degree of winding stagger, reducing leakage flux in the air outside the core, while improving converter efficiency and power density.
