摘要： A matrix transformer particularly suited to large voltage step-down, high current applications achieves increased good current sharing uniformity or air gap and electrical characteristics and reduced or eliminating termination losses, core losses and winding losses with a unitary magnetic core structure featuring sheets of magnetic material and a two-dimensional array of pillars on which windings, oriented in opposite directions on pillars that are adjacent in orthogonal directions, can be formed or placed comprising metallization on or embedded in a printed circuit board (PCB) structure. Magnetic flux density is reduced by at least one-half by dividing the magnetic flux in each pillar into two paths of increased width in the sheets of magnetic material. Magnetic flux density may be further decreased and flux uniformity improved by extending the sheets of magnetic material beyond a periphery defined by the pillar array.

摘要： The invention comprises a high frequency inductor filter apparatus coupled with an inverter yielding high frequency harmonics and/or non-sixty Hertz output. For example, an inductor/converter apparatus is provided using a silicon carbide transistor that outputs power having a carrier frequency, modulated by a fundamental frequency, and a set of harmonic frequencies. A filter, comprising an inductor having a distributed gap core material and optional magnet wires, receives power output from the inverter/converter and processes the power by passing the fundamental frequency while reducing amplitude of the harmonic frequencies.

摘要： The coil component includes a magnetic core 130 and conductors 210 and 220. The magnetic core 130 includes through-holes that are made by grooves 111 and 112. The conductors 210 and 220 are provided in the grooves 111 and 112, respectively. The magnetic core 130 includes a nonmagnetic portion in which the grooves 111 and 112 are communicated, and a distance between the conductors 210 and 220 through the nonmagnetic portion is shorter than a distance between the conductors 210 and 220 in surfaces 110c and 110d in which the conductors 210 and 220 are exposed. Therefore, necessity to provide a large cavity in the magnetic core is eliminated, and a risk of the short circuit between terminal electrodes exposed in the surfaces 110c and 110d is also eliminated.
