  • Patent number: 12218185
    Abstract: To provide a thin film capacitor in which warpage is less likely to occur. A thin film capacitor includes: a metal foil having roughened upper and lower surfaces; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a dielectric film covering the lower surface of the metal foil and made of a dielectric material having a thermal expansion coefficient smaller than that of the metal foil; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the first dielectric film without contacting the metal foil. The lower surface of the metal foil is thus covered with the dielectric film having a small thermal expansion coefficient, thereby making it possible to prevent the occurrence of warpage.

  • Patent number: 12176752
    Abstract: A plurality of UPSs are connected in parallel between an AC power supply and a load. The UPSs each include a first switch connected between the AC power supply and an AC node. During the first power feeding mode, a control device turns on the first switch, and controls a power conversion device so as to receive AC power from the AC node and generate AC power. During a second power feeding mode, the control device turns off the first switch, and controls the power conversion device so as to receive DC power from a power storage device and generate AC power. When the AC power supply recovers during the second power feeding mode, the control device successively switches the plurality of UPSs to the first power feeding mode by successively turning on a plurality of the first switches each of which corresponds to each of the plurality of UPSs.

  • Publication number: 20230260698
    Abstract: To provide a thin film capacitor having high flexibility. A thin film capacitor includes: a metal foil having a roughened upper surface; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the dielectric film without contacting the metal foil. The particle diameter of crystal at a non-roughened center part of the metal foil is less than 15 ?m in the planar direction and less than 5 ?m in the thickness direction. This can not only enhance the flexibility of the metal foil to reduce a short-circuit failure in a state where the thin film capacitor is incorporated in a multilayer substrate but also enhance positional accuracy.
