Comprise at transformer device structure of the present invention:
1, permeable section---many UU type ferrite magnetic core bondings realize super high power:
Ferrite: ferrite is a kind of pottery ferromagnetic material with crystal structure, and it has very high resistivity, and eddy current loss can be ignored, and uses under being highly suitable for high frequency state;
Magnetic core geometries: UU, the coil of this kind of magnetic core is not surrounded completely by magnetic core, air can pass through from centre, transformer good heat dissipation, and square-section is shorter by 11% than equal area circular cross section wire length, when the identical number of turn, coil impedance also want little by 11%, and copper loss and temperature rise also smaller comparatively speaking.In order to realize super high power, we, by the use that sticks together after many core grindings, can increase the sectional area of magnetic core.
2, current-carrying part---the stranded litz wire multiply scheme in parallel and red copper foil of many fine rules effectively can reduce the impact of kelvin effect and proximity effect under high frequency condition:
Kelvin effect and proximity effect: under high frequency condition, this effect can make current convergence in the sub-fraction of conductor cross-section, thus increases copper loss, causes coil temperature rise too high.
The stranded litz wire of many fine rules can reduce the impact of kelvin effect and proximity effect, multiply parallel connection can increase wire total sectional area when operating current is larger.
Get the Copper Foil of suitable thickness during super high power big current, be cut to and require that size uses.
In this series, calculate a series of different operating current by measure, add rope-lay strand by rope-lay strand, red copper foil adds rope-lay strand, red copper foil adds the single coiling of the multiple combinations such as red copper foil or several paralleled conductor realizes.
