In transformer device structure of the present invention, comprise:
1, magnetic conduction part---many bonding realization super high powers of UU type ferrite magnetic core:
Ferrite: ferrite is a kind of pottery property ferromagnetic material with crystal structure, and it has very high resistivity, and eddy current loss can be ignored, and is highly suitable under the high frequency state to use;
Magnetic core geometries: UU; The coil of this type magnetic core is not surrounded by magnetic core fully, and air can pass through from the centre, the transformer good heat dissipation; And the square-section is than equal area circular cross-section conductor length short 11%; Under the situation of the identical number of turn, it is little by 11% that coil impedance is also wanted, and copper loss and temperature rise are also smaller comparatively speaking.In order to realize super high power, the use that sticks together after we grind many magnetic cores can increase the sectional area of magnetic core.

Kelvin effect and proximity effect: under high frequency condition, this effect can make current concentration on the sub-fraction of conductor cross-section, thereby increases copper loss, causes coil temperature rise too high.
The many stranded litz wires of fine rule can reduce the influence of kelvin effect and proximity effect, but the multiply parallel connection increases the lead total sectional area when operating current is big.
Get the Copper Foil of suitable thickness during the big electric current of super high power, be cut to and require size to use.
In this series, calculate a series of different working electric currents by measure, add through rope-lay strand that multiply twisted wire, red copper foil add the multiply twisted wire, red copper foil adds the single coilings of multiple combination such as red copper foil or several paralleled conductor is realized.
