As shown in FIG. 2, the magnetic capacitance measurement includes a -first magnetic electrode (10), a second magnetic electrode 22A, and a dielectric trace between the first magnetic electrode 210 and the first magnetic electrode 22G. The magnetic conductive material comprises a neodymium conductive material (for example, a rare earth element), and the second magnetic electrodes 21〇, 22〇 are magnetized by a suitable applied electric field to make the first and second magnetic electrodes A magnetic dipole is formed in 210 220 (disengaged coffee (10) 215, milk magnetic dipole 215 225. This forms a magnetic field inside the magnetic capacitor 2〇〇, which can affect the movement of charged particles, thereby suppressing the magnetic capacitance. Leakage current; dielectric layer 23 is made of a dielectric material (such as · oxygen contact (TK) 3), titanium oxide (BaTi〇3) or - semiconductor material (for example: oxidized stone fine c〇n〇 Xide" is configured to separate the first magnetic electrode 210 and the second magnetic electrode 22A to accumulate charge at the first magnetic electrode 21 〇 and the second magnetic electrode 220 to store potential energy. The following will be directed to the operation of the magnetic capacitor. The principle of 201018065 is further explained. The magnetic capacitor mainly uses the magnetic poles 215 and 225 arranged neatly to form the magnetic % 'the electrons stored in the first magnetic electrode 210 and the second magnetic electrode no are respectively arranged in the spin-direction and arranged neatly, so that a large amount of storage can be stored. The electric charge, in turn, greatly increases the energy storage density. Note that the magnetic dipoles 215, 225 shown in Fig. 2 are respectively directed in the direction of the subtraction, however, this is not a limitation of the present invention, in practice, the magnetic dipole The directions of 215 and 225 are not limited. For example, the magnetic dipoles 215 and 225 can also point in the same direction. The capacitance value of the conventional capacitor C is the area of the capacitor, the dielectric constant, the er and the thickness d. For the decision, please refer to Equation 1: η _ T~ Ui) Compared with the conventional capacitor 'magnetic capacitor 200 is equivalent to changing the dielectric constant of the dielectric layer by the action of the magnetic field to increase its capacitance value; In one embodiment of the present invention, the first magnetic interface between the first magnetic layer and the dielectric layer 23, and the second interface between the second magnetic electrode 22 and the dielectric layer 23 are both a flat surface, thus by stepping up by increasing the surface area A 200 l of the magnetic capacitance of the capacitor. Please refer to FIG. 3, which is a comparison diagram of the magnetic capacitor of the present invention and other conventional energy 201018065 storage media. As can be seen from Fig. 3, the magnetic capacitor has a relatively high energy storage density compared to the conventional capacitor and the super capacitor. Please refer to FIG. 4, which is a schematic structural view of an embodiment of the first magnetic electrode 210 shown in FIG. As shown in FIG. 4, the first magnetic electrode 210 is a three-layer structure including a first magnetic layer 412, an isolation layer 414, and a second magnetic layer 416, wherein the isolation layer 414 is made of a non-magnetic material. The first magnetic layer 412 and the second magnetic layer 416 comprise magnetically conductive materials, and the first and second magnetic layers 412 and 416 are magnetized by different applied electric fields to make them first. Magnetic dipoles 413 and 417 are formed in the second magnetic layers 412 and 416, respectively, and the magnetic dipoles 413 and 417 together form a magnetic dipole 215 of the first magnetic electrode 21〇. In the preferred embodiment of the invention, the magnetic dipoles 413, 417 are respectively directed in opposite directions (as shown in Figure 4) to suppress leakage current of the magnetic capacitor 2〇〇. It is to be noted that the structure of the first magnetic electrode 21 is not limited to the aforementioned three-layer structure (the first and second magnetic layers 412, 416 and the isolation layer 414). In other embodiments of the present invention, the first The magnetic electrode 21A can be a multi-layer structure, more specifically, the 'the magnetic electrode 210 can be composed of a plurality of magnetic layers and a plurality of isolation layers continuously intersecting = stacking' and then adjusting the magnetic dipole direction of each magnetic layer. In order to suppress the leakage current of the magnetic valley 200, even the effect of almost no leakage current is achieved, and this design change is also pertaining to the nozzle of the present invention. Further, the structure of the second magnetic electrode no can be adopted as the structure of the fourth magnetic electrode 21, so that the contents of the description are simple. The detailed description of the structure of the magnetic electrode 22G is omitted here. 201018065 Please refer to FIG. 5, which is a schematic diagram of an embodiment of an input DC power supply module 1〇2 of the present invention. As shown in the top, the input DC power supply module 1〇2 is realized by a magnetic capacitor module including a plurality of magnetic capacitors 200, and the magnetic capacitors 2 are electrically connected to each other in an array manner.

The voltage detecting unit 614 is connected in parallel to the S-heavy load to detect the voltage change of the output DC power source P〇. The control unit 616 is consuming the current detecting unit 612, the voltage detecting unit 614, and the switching switch 606 for controlling the switching frequency according to the current change condition of the output DC power source and the voltage change condition. The control unit 610 monitors the power condition of the load 610 through the voltage detecting unit 614 and the control unit 616 to adjust the switching frequency of the control switching switch 6〇6 to achieve the required output DC power Po, which satisfies the power demand of the load 610. It should be noted that the DC power conversion device 1A of FIG. 1 and the 々 π power conversion device 60 of FIG. 6 are embodiments of the present invention, and those skilled in the art can make different changes according to the present invention. Not limited to this. Any DC power conversion device and electronic device that can achieve the same effect as the above-described disclosed component φ and the architecture are all within the protection scope of the present invention. In summary, in the present invention, the power storage unit of the DC power conversion device uses a capacitor design to avoid the energy consumption disadvantage of using the resistor to save system power and, more importantly, to have a large energy density and volume. Small and lightweight magnetic capacitors provide fast and stable power supply and reduced device size. The above description is only the preferred embodiment of the present invention, and all the (four)izations and modifications made in accordance with the patent application scope of the present invention are all covered by the present.
