摘要： PURPOSE:To reduce the noise of harmonic radiation and to prevent its adverse effect inflicting on the circumferential electronic apparatuses by a method wherein the quality of material of a first and a second cores is properly selected, the permeability of the first core is made higher than that of the second core in the fundamental frequency of coil exciting circuit, and the frequency in a harmonic region of the former is made lower than the latter. CONSTITUTION:The quality of material of a first core 1 and a second core 2 is selected in such a manner that the permeability of the first core 1 becomes higher than that of the second core 2 in the fundamental frequency of coil exciting current and that the permeability of the former becomes lower than that of the latter in a higher harmonic region. Accordingly, the iron loss of the device is suppressed in the fundamental frequency of coil exciting current, and heat generation become small. Also, the permeability of the second core 2 becomes higher in the frequency of the higher harmonic region, and leakage to outside of magnetic flux generated by the frequency of coil exciting current in the higher harmonic region is reduced. As a result, higher harmonic radiant noise is reduced, and the adverse effect inflicting on the circumferential electric apparatuses and the increase in power consumption of the device can be prevented.

摘要： PURPOSE:To increase the variable amount of inductance by a method wherein a wire- wound bobbin is provided, and recessed and protruding parts, which will be attached to said bobbin by being pinched from both ends, are formed side by side in the circumferential direction on the butt-together surfaces of the inner magnetic path and the outer magnetic path. CONSTITUTION:Pot cores 11 and 12 are composed of inner magnetic paths 13 and 15, which pass through a bobbin 10, and the outer magnetic paths 14 and 16 which are externally fit to the bobbin 10. The butt-together surfaces 17, 18, 19 and 20 of the inner magnetic paths 13 and 15, and the outer magnetic paths 14 and 16 are divided into two parts of protruding parts 21, 23, 24 and 25, and recessed parts 22, 24, 26 and 28 in circumferential direction. As the distance between magnetic bodies becomes smaller and an opposing area becomes wider, the magnetic reluctance becomes smaller; the magnetic reluctance becomes larger in the order of the state of theta=0 deg. (the state wherein the protruding parts 21 and 25, and the protruding parts 23 and 27 are opposingly positioned) theta=90 deg. and theta=180 deg., while the inductance becomes lower. At the same time, the variable amount of inductance is increased compared with the case of the where the recessed and protruding parts are formed only in the inner magnetic parts as by the method heretofore in use.

摘要： PURPOSE:To restrain eddy current loss and reduce temperature rise, by a method wherein the region where the eddy current flows is limited when magnetic flux interlinks a conductor foil, by forming the conductor foil in a slender type, and arranging a lot of the foils on an insulating sheets so as to keep insulation intervals. CONSTITUTION:A pair of insulating sheets 2 wherein a lot of slender conductor foils 1 are arranged so as to keep insulation intervals and electrodes 3 are formed on both ends of the conductor foils 1 are prepared. These insulating sheets 2 are stacked and wound, in the manner in which the longitudinal direction of the conductor foil 1 is made the winding direction. Hence the conductor foils 1 arranged on each insulating sheet 2 function as capacitors. When currents are made to flow in the same direction through the conductor foils 1 on each insulating sheet 2, the function as choke coils is obtained. The conductor foils 1 have a slender type and arranged on the insulating sheet 2 so as to keep insulation intervals in the above manner, so that the region where a current flows is limited when magnetic flux interlinks the conductor foils 1. Thereby eddy current loss is restrained, and temperature rise can be reduced.

CONSTITUTION:A yoke core 10 whose section is H-shaped and a pair of bar- shaped exciting cores 11 and 12 are both made of Mn-Zn ferrite. For the exciting cores 11 and 12, gaps 15 and 16 are made at both sides between itself and the flanges 13 and 14 of the yoke core 10. Furthermore, windings 17 and 18 are wound, through bobbins, around each exciting core 11 and 12, and currents are applied so that the magnetism may be reduced at the foot 9 of the yoke core 10. This way, an electromagnetic device, where bellow magnetic fluxes do not interfere with each other, can be constituted, and it can be miniaturized and lightened, with high performance maintained.

摘要： PURPOSE:To prevent both increase in power consumption and heat generation on circumferential components by a method wherein a closed magnetic circuit is formed of a first L-type coil, which passes through a coil, and a second L-type core provided outside the core, and a gap is formed by opposing the side face of both end parts of the second L-type core to both edge faces of the first L-type core. CONSTITUTION:A closed magnetic circuit is formed of a first L-type core 2, which passes through a coil 1, and a second L-type core 3 provided outside the coil, and gaps A and B are formed by opposing the side faces of both edge parts of a second L-type core to both edge faces of the first L-type core 2 respectively. Accordingly, the magnetic flux generated on the first L-type core 2 by the coil 1 is transferred from one edge face to the side face of one edge part of the second L-type core 3 through the intermediary of the gaps, the magnetic flux then returns from the side face of the other edge part of the second L-type core to the other edge face of the first L-type core 2 through the gaps, and leakage magnetic flux is reduced. As a result, the increase of power consumption and the heat generation of the circumferential components can be reduced.
