(4) Second middle/view A magnetic core The B core is a toroidal core, the toroidal core is a whole 'striped billet, (4) ^ shape, the magnetic field line can be set in the ship ring (10) - as shown above, or the inductance Phase one ==::== In the reduction of volume, it will reduce the goodness of Ni//, and it will reduce the volume of the magnetic force by the Μ 的 同时 同时 / / / / / / , 圏 圏In this way, when the second force line passes through the output voltage for the second time, it is existing in other parameter pastes, and the output stage of the core-core seam _ is twice or more than the output voltage, that is: age, winter For the 201123225 integer. The magnetic circuit loop assembled by the magnetic core assembled with this magnetic core has already produced an electric lifting process. In this kind of magnetic core, the lifting and lowering of the magnetic core is not completely dependent on the line: It is said that the transformer has a two-fold or more-fold efficiency in the case where the core volume is constant and the number of turns of the input stage and the output stage coil is constant. = 咖 咖 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The two sides of the foot are not magnetic 1 because the magnetic line is looped twice, the length of the core is halved, and the equivalent magnetic path length is not the same. The cross-sectional area of the magnetic core is equal, and the volume of the existing transformer is half - the coil The inductance is the same, the number of turns is the same, the applied circuit topology is unchanged, and the number of turns of each group of coils is reduced by half. The width of the colloid winding groove is reduced by half, the volume is reduced, the copper consumption is reduced, and the power density is doubled. Similarly, in the inductor, the magnetic core is used, and the inner magnetic line of the magnetic core can also realize (4) excitation. After the magnetic core is lightly passed through the coil-time, the magnetic line generated by the post can be traversed through the coil again. In this way, the surface line can cost more than two dollars, and the magnetic lines of more than two money are connected in series. 'The coil generates two excitations to the core. This type of electricity can be narrowed—the area of the half-hysteresis loop is reduced, and the magnetic hysteresis is reduced. , corrected the linear hiddenness of the hysteresis loop and extended the magnetic circuit. It is possible to adjust the inductance by adjusting the length of the magnetic circuit, not just relying on the gas-segment, because the gas gap is less, the core loss is less, and the signal distortion is less. [Embodiment] Hereinafter, specific embodiments of the present invention will be described in conjunction with the accompanying drawings and embodiments. In the following embodiments, only Lin is more clearly defined in the present invention, and Wei uses this to limit the scope of protection of the present invention. As shown in Figures 7 to 9, the principle of generating a series excitation is that it is known that a coiled coil that generates electricity generates a magnetic field whose magnetic field strength is Η, h = ni / l, (where I is a warp coil The current 'N is the number of turns of the coil, and L is the axial length of the coil). Internally added magnetic conductor, 201123225=The force line is redistributed by the magnetic conductor. According to the magnetic permeability of the magnetic conductor material, the magnetic field strength of the magnetic material is not _, and the magnetic induction intensity in the magnetic material conductor is described as _, (u is the magnetic permeability of the magnetic conductor, which is recorded as magnetic permeability). When the current in the field coil is not a constant current source but changes, the measured periodic change process can hide the well-known hysteresis loop, as shown in Figure 8, (Ηϋ 。. In the absence of GAy' according to the period duality, When the magnetic conductor exhibits remanence, the force corresponding to the leakage of the coil Η". For the magnetic line to be as close as possible to the end-to-end closure, the composition is closed, reducing the conductor to make a ring paste or EE, EI, ER, Ep, rm Etc., in order to benefit the two parts: to become a closed closed magnetic circuit. When the middle section of the magnetic circuit has an air gap GAp, the hysteresis loop has or,: I appears βΓ decreases, & What is shown is the continued tenacity. This is not ^. Why is there no temperament, Hr and βΓ have physical versus na, there is change from the time, rr is not deleted ^ Is there any way to do (four) cap less? Yu, The invention has the following improvements: The effect of the lion's rule is set off, and the ϋ ϋ ϋ 线圈 线圈 线圈 磁 磁 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若 若Part of the hysteresis loop of the retroreflection changes. The magnetic surface of her appearance, except for (10) turn, only the conductor of the doped material is issued. f as an excitation, thereby changing the shape of the hysteresis loop? The material of the magnetic conductor cannot be changed by the magnetic circuit of the magnetic conductor of the stagnation loop, and the magnetic gap is changed to change the magnetic circuit t. It is not changing the material f of the magnetic conductor, so only the magnetic circuit can be changed. For the further analysis, the magnetic circuit is measured when the hysteresis is measured, which is approximated by the short side of the coil or the magnetic head of the dagger. Recorded, because it is changed by __ bundle, it has less practical significance, and the magnetic circuit passes through the line of the invention only once from the coil. = The head ΓΓ coil passes twice. The invention is bridged. Force & Reduced Qu-Head 朿 'The physical analysis process of the present invention: As shown in Fig. 1G, the positive thin ring is equally divided into 201123225.

The 1/4 of the line is because the cross-sectional area is reduced by - half, and the length of the magnetic field line is increased by - times. # When the coil is wound, the lower part is also enveloped. 'Because of the series relationship, it is twice the inductance of Figure 1(). Because the size of the inductor directly determines the amount of conversion power, in the figure, when the cross-sectional area is constant, the length of the magnetic field line is reduced by half, that is, the round % shuttle is reduced by half. In order to achieve the same inductance as in Figure 1 It is necessary to reduce the number of turns in half - which means that the magnetic core of the series excitation can achieve the same excitation with a smaller number of turns, and the same (4) the remaining power is readable, because the current of the coil is reduced, so the Hr change is verified.

Reducing the magnetic field that can be obtained at the time... The invention has designed five physical models as shown in Fig. 12. The five types of materials can be used for the five kinds of lion towns (because of the analysis of the miscellaneous (four), the magnetic ring is generally used. The inductance is used to calculate the inductance of the magnetic permeability Ue). Figure 12-1 shows that the lower half of the series annular core is not wound around the coil. The inductance is: ALi=4^Ve(Ae/2)/(Le+ Le)=l/4AL〇; Figure 12-2 shows the inductance of the lower half of the existing new double-ring core without being wound around the coil: A L2=4 7rVe(Ae/2)/(Le+ Le)=l/2AL0 ; The magnetic pattern in the coil, the upper and lower cores is the same as the existing double-ring new core, and the upper and lower halves are wound in opposite directions.

Therefore, in the application of the spotted spot ~ face ^ horizontal thin =:: Τ: Γ, has not changed; the frequency of the work has not changed; the coil is induced by the same voltage as the electric 戌 L clock 4, the present invention needs to reduce the number of turns For 10,000/2Ν, ^ is the inductor L, the number of turns, and the number of turns is the same, the measured electric power is twice, then under the --a material, there will be two systems. When the inductance is high, the magnetic permeability Ue is high, so the tandem relationship is increased by η times. The human "- (four), the same in series η times, in order to achieve the effect of the surface 2-5 magnetic ring, to miniaturize the magnetic device, the present invention redesigned the core EE, EI, ER, ΕΡ, abdomen, etc. The specific method is similar. ° When the current pressure is just going to take the _, the new long scorpion becomes the old transformer - half and above, the hole in the skeleton of the transformer is unchanged, and the cross-sectional area of the magnetic core is equal, in order to reduce the opening Model, try to share the standard of financial specifications, such as J ^^^ER28/28 5 '^/J'7 17*6% 5 363⁄4 ; 曰 is EE19/16, reduced by ·; the number of turns of each coil is reduced , Nana factory inductance - like, the air gap is opened on two mutually connected magnetic circuits, carrying DC field, not 201123225 is easy to saturate (if separated on two magnetic circuits, the air gap magnetic circuit is mutually connected, the core is easy to saturate) And to adjust the inductance, the turns ratio is the same, the applied circuit topology form is unchanged, the skeleton winding slot _ less, the volume is reduced, the copper consumption is reduced, the power density is increased.
