Description
エネルギー貯蔵=1/2*L*I2 (式1)
粒子の周囲に絶縁材、結合材および潤滑材によって形成した先に記載のギャップに加えて、粒子組成および粒子サイズの選択によってエネルギー貯蔵を最大化する。圧粉技術によって飽和特性がすぐれたものになるため、対応する印加電流に対してインダクタンスを高く維持でき、貯蔵エネルギーが最大化する。
L=L1+L2±2*K*(L1 *L2)0.5 (式2)
式中、+または−は結合が和動か差動かに依存するものである。L1およびL2はそれぞれ第1巻き線部および第2巻き線部のインダクタンスを表し、Kは結合係数を表す。従って、変圧器10は、第1巻き線部および第2巻き線部両者のインダクタンスがLで、結合が完璧で和動の場合には、4Lを与えることになる。
