Abstract
Many circuits, such as power supply circuits, generate ripples and noise derived from switching. Therefore, power inductors and filter inductors are essential to these circuits. The authors have developed "Hybrid inductor" that maintain high inductance over a wider frequency band than conventional inductors. The hybrid inductor not only has excellent frequency characteristics, but also has excellent DC bias characteristics. As a result, the inductance of the hybrid inductor increased by 19.6% near DC and 52.0% at 30 MHz, compared to the conventional inductor. In addition, at IDC = 60 A, the inductance increased by 32.6%.
