    摘要： Provided are embodiments for a system and method (500) for reforming an electrolytic capacitor (C1, C3, C4). Embodiments can include disabling a primary switch (102, 302, 402), wherein the primary switch (102, 302, 402) selectively couples a power supply (104, 304, 404) to the electrolytic capacitor (C1, C3, C4), and providing a signal to one or more reforming switches (RR1, RR2, RR3, RR4, RR5) to control the one or more reforming switches (RR1, RR2, RR3, RR4, RR5). Embodiments can also include completing the reforming process based at least in part on a detection of a voltage of the electrolytic capacitor (C1, C3, C4) or a duration of time, and disabling the one or more switches responsive to completing the reforming process.

    摘要： The present invention provides a method for producing a capacitor element having good LC characteristics, wherein, after a chemical conversion process to form a dielectric layer on the surface layer of an anode body obtained by forming a powder mainly comprising tungsten, followed by sintering, a semiconductor layer and a conductor layer are sequentially formed on the dielectric layer; an etching process is conducted before forming the dielectric layer to remove a natural oxide film formed on the surface layer on the outer surface and on the surface inside the pores of the anode body so as to adjust the film thickness to a range of 0.5 to 5.0 nm; and the chemical conversion process is conducted at a temperature from -4 to 18°C for 7 to 110 minutes after reaching a predetermined voltage.

    摘要： There is provided a method of manufacturing a solid electrolytic capacitor including: forming a conductive polymer layer on a surface of a metal pellet; and forming a dielectric layer between the metal pellet and the conductive polymer layer. Because the conductive polymer layer is directly formed on the surface of the metal pellet, the conductive polymer layer can be uniformly formed, and because there is no need to form an electrode on the surface of the dielectric layer, the process can be reduced. In addition, because the uniform polymer film is formed irrespective of the size of metal pores and the shape of the capacitor, a capacity of the capacitor can be maximized.
