A filter circuit is required to suppress noise and have high gain attenuation characteristics in a wide band. Gain attenuation decreases because the relative permeability of an inductor core employed in a filter circuit drops sharply as drive frequen

Inductors used for power supplies can be miniaturized by increasing the frequency. However, as the frequency increases, the loss in the inductor increases, which hinders the improvement of efficiency. This study suggests a flux path control technolog

Alternating current (AC) copper losses in motors increase with carrier frequency of the pulse width modulation (PWM) and are further increased by leakage flux of the permanent magnet. Therefore, AC copper losses increase with motor speed. Conventiona

Increasing the switching frequency of direct current–direct current converters is effective in reducing the size of magnetic components used in converters. However, as the switching frequency increases, the loss and heat generated by the magnetic c
