Claims (1)
- コイル部品を接続したDC−DC回路を有するマルチフェーズ回路であって、前記コイル部品は、磁性材料を粉末にして表面を絶縁皮膜で覆い、結合剤を混ぜて加圧成形した磁心と、前記磁心に埋設したコイルと、前記コイルに接続または延設し、前記磁心より突出させた端子部とを備え、前記コイルは、前記磁心に複数埋設するとともに、互いに並列接続させ、各々の前記コイルが共同で前記DC−DC回路における電圧変換用部品として機能するとともに、温度特性および回路効率は、複数の前記磁心に単体で埋設した各々の前記コイルが共同で前記DC−DC回路における電圧変換用部品として機能する場合の温度特性および回路効率と略同等であり、複数の前記コイルは、積層され、かつ、巻軸方向を同方向にするとともに、巻軸が同一直線状に位置するように配置され、前記コイル間に、前記磁心の透磁率よりも小さい透磁率であって、前記コイルの対向面に貫通孔を有するとともに、前記磁心の両端と接触させず、前記磁心の端部との間にギャップ部を有するスペーサを介在させたマルチフェーズ回路。
