Can find out that application number is that 200710186467 Chinese patent also is that two magnetic cores are stitched together, realize inductance and transformer to separate lotus root magnetic integrated, what use above is the EI magnetic core, what use below also is EI type magnetic core.This magnetic integrated approach can be used on the small-power power; But because the most suitable application of high-tension transformer magnetic core UU type magnetic core; The secondary winding is unsuitable too many; Therefore please number be the 200710186467 disclosed transformers and the magnet integrate construction of inductance, not be suitable for use in large power supply especially on the high voltage source.
The utility model content
In view of the above problems, the purpose of the utility model provides a kind of especially magnetic integration apparatus on the high voltage source of large power supply that is suitable for use in.
An aspect according to the utility model provides a kind of resonant inductance and high-tension transformer magnetic integration apparatus, comprises stacked U type magnetic core and EE or EI type magnetic core from top to bottom; Wherein,
Open Side Down for said U type magnetic core, and on two side columns of said U type magnetic core, twine high-tension transformer former limit winding and secondary winding respectively;
The U type opening of said U type magnetic core is placed on the lateral column or center pillar of said EE or EI type magnetic core; And there is not winding on the EE that said U type opening is put or the lateral column of EI type magnetic core or the center pillar; On two other post of said EE or EI type magnetic core, have air gap and be wound with two inductance windings respectively, said two inductance windings magnetic flux on the post that does not have winding of said EE or EI type magnetic core is opposite, size is identical.
In addition, preferred scheme is, in said U type magnetic core, with the magnetic core of U type ferrite as high-tension transformer; In said EE or EI type magnetic core, with EE or EI type ferrite as the resonant inductance magnetic core.
Moreover preferred scheme is that the ratio of the two-part magnetic resistance of resonant inductance coiling is identical with the turn ratio of said two inductance windings.
Utilize above-mentioned resonant inductance and high-tension transformer magnetic integration apparatus according to the utility model, resonant inductance and high-tension transformer that can volume is bigger integrate, and reduce volume, improve power density.
In order to realize above-mentioned and relevant purpose, one or more aspects of the utility model comprise the characteristic that the back will specify and in claim, particularly point out.Some illustrative aspects that following explanation and accompanying drawing have specified the utility model.Yet, the indication of these aspects only be some modes that can use in the variety of way of principle of the utility model.In addition, the utility model is intended to comprise all these aspects and their equivalent.
Description of drawings
Through with reference to below in conjunction with the explanation of accompanying drawing and the content of claims, and along with the more complete understanding to the utility model, other purpose of the utility model and result will understand more and reach easy to understand.In the accompanying drawings:
Fig. 1 is the magnet integrate construction sketch map of a kind of transformer of the prior art and inductance;
Fig. 2 is according to the resonant inductance of the utility model embodiment and high-tension transformer magnetic integration apparatus structural representation.
Identical label is indicated similar or corresponding feature or function in institute's drawings attached.
Embodiment
Below will combine accompanying drawing that the specific embodiment of the utility model is described in detail.
Fig. 2 shows according to the resonant inductance of the embodiment of the utility model and high-tension transformer magnetic integration apparatus structural representation.
Owing to the volume of resonant inductance and high-tension transformer is all bigger, integrate to reduce volume, improve power density, but high-tension transformer and resonant inductance are integrated, not only will consider decoupling zero, also will consider insulation processing.
