ける磁気抵抗が上がり、温度が上昇することになる。<Prior art> Coils that can be used in DC-DC converter devices, etc. have the drawback of passing several tens of watts of power, resulting in a large amount of VC heat generation and large magnetic loss. There was also a drawback that magnetic loss was large in the equipment used. In that case, the volume is ¥115! There will be a temperature difference between the wire-wound portion and the unwound portion, and if a gap is provided, the magnetic resistance at the gap portion will increase and the temperature will rise.

て磁気損失を招くという欠点があった。In the above-mentioned high-frequency power coil, the temperature TA at the part A of the gap 03 and the temperature TB at the part B where the winding 02 is applied are as follows from an experiment: TA = 250tll:
, Tn = 200℃, when a temperature difference occurs in each part of the same ferrite magnetic core 01, stress is added, which causes distortion and causes magnetic loss. There were drawbacks.

, the 800% becomes 500rn% when the 7-elite magnetic core 01 is cut at a predetermined position excluding the winding section gain as shown in Fig. 2.
The existence of stress is eroding the force.

電力用コイルを提供するものである。Measures to Solve the Problems〉 Unexploded BA was developed in view of the above-mentioned circumstances, and is designed to reduce the temperature between the winding part of the ferrite magnetic core and the part without winding in a high-frequency power coil. In order to eliminate the difference, a cut part is provided at a predetermined position except for the winding part of the ferrite magnet, and a ferrite block that cancels thermal expansion is joined to this cut part.The ferrite joint part causes distortion, The present invention provides a high-frequency power coil that reduces magnetic loss due to stress.

The ferrite block 2 at the cut portion offsets the thermal expansion due to the temperature difference between the wire and the non-wire portion.
