Description
Technical field
This utility model belongs to electrical safety field, is specifically related to the winding construction of a kind of flat surface transformer, and the winding construction particularly to a kind of low-loss high-frequency planar winding iron-core transformer designs。
Background technology
Flat surface transformer has: low moulding, low-loss, low leakage inductance, high frequency characteristics are good, be suitable for the feature of large-scale production；Design high frequency planar transformator it is crucial that require leakage inductance and the distribution capacity of high frequency planar transformator are effectively suppressed, namely reduce leakage inductance energy and distribution capacity electric field energy that high-frequency effects produce, the total losses reaching high frequency planar transformator are minimum；Therefore research and develop a kind of low-loss, leakage inductance is few, distribution capacity effectively suppresses, the winding construction of the low-loss high-frequency planar winding iron-core transformer of rational in infrastructure, design science has Practical significance very much。
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide that a kind of low-loss, leakage inductance are few, distribution capacity effectively suppresses, the winding construction of the low-loss high-frequency planar winding iron-core transformer of rational in infrastructure, design science。
The purpose of this utility model is achieved in that the winding construction design of a kind of low-loss high-frequency planar winding iron-core transformer, it includes magnetic core, the outside of described magnetic core is wound with winding, described winding includes armature winding A, armature winding B, secondary windings, it is provided with insulating barrier A between described armature winding A and secondary windings, it is provided with insulating barrier B between described armature winding B and secondary windings, described armature winding A, the displacement that the relative middle secondary winding of armature winding B upper and lower two-layer armature winding staggers is d, described armature winding A, armature winding B is coaxially arranged above and below with middle secondary windings, described armature winding A, spacing between armature winding B and secondary windings is h。
Described armature winding A is identical with the structure of armature winding B。
The described half that displacement d is armature winding A width。
Described magnetic core is EI core structure。
Described insulating barrier A and insulating barrier B is provided with RF4 substrate。
The beneficial effects of the utility model: high frequency planar transformator of the present utility model, even if there being little leakage inductance, it is also easy to produce relatively larger leakage impedance, therefore, magnetic core uses closes EI type square structure, and its leakage inductance is little, concentrates in magnetic core because the magnetic flux of closed iron core is substantially all, the interference that magnetic field of tube outside interference does not invade generation from which direction all can cancel each other, because the disturbing magnetic field of outside is all divided into both direction to pass through in magnetic core；High frequency planar transformator distribution capacity is except being directly proportional to the surface area of armature winding A, armature winding B, also being inversely proportional to winding layers spacing h, when the half that displacement d is armature winding A width, dynamic capacity is zero, now, the window activity coefficient of high frequency planar transformator is close to one；Total this utility model has low-loss, leakage inductance is few, distribution capacity effectively suppresses, the advantage of rational in infrastructure, design science。
