Fixed Capacitor Patents (Class 361/301.1)
  • Publication number: 20130342955
    Abstract: A semiconductor structure may implement a metal-oxide-metal capacitor. When layer design rules change from one layer to the next, the structure may change the direction of the interleaved plates of the capacitor. For example, when the metallization width or spacing design rules change from layer M3 to layer M4, the structure may run the capacitor traces in different directions (e.g., orthogonal to one another) on M3 as compared to M4. Among the layers that adhere to the same design rules, for example layers M1, M2, and M3, the structure may run the capacitor traces in the same direction in each of the layers M1, M2, and M3. In this way, the capacitor traces overlap to large extent without misalignment on layers that have the same design rules, and the structure avoids misalignment of the capacitor traces when the design rules change.

Such bus structures are very well suited for inverter topologies used to convert from DC to AC power and a capacitor is needed to minimize ripple on the DC bus. The present invention provides a method of integrating an annular form factor wound film capacitor into a parallel bus structure to provide a compact geometry with minimal inductance. Furthermore, the capacitor acts as the dielectric spacer between the bus plates, which eliminates the need for separate capacitor terminals and provides the lowest possible profile.

  • Patent number: 8194387
    Abstract: A multi-layered capacitor includes three or more capacitor layers. A first layer includes a first DC-biased, tunable capacitor. A second layer, acoustically coupled to the first layer, includes a second DC-biased, tunable capacitor. A third layer, acoustically coupled to the second layer, includes a third DC-biased, tunable capacitor. Each dielectric of the first, second, and third capacitors has a resonance of about the same frequency, within 5%, and inner electrodes of the first, second, and third capacitors have a resonance of about the same frequency, within 5%. The resonance of each layer is a function of at least thickness, density, and material. The first, second, and third layers are biased to generate destructive acoustic interference, and the multi-layer capacitor is operable at frequencies greater than 0.1 GHz.

  • Publication number: 20120099240
    Abstract: A magnetic capacitor includes two electrode layers, an insulator layer, and one or more magnetized layers. The insulator layer is located between the first electrode layer and the second electrode layer. The one or more magnetized layers include one or more ferro-magnetic elements that are magnetized. The one or more magnetized layers are located so that the one or more ferro-magnetic elements apply a magnetic field to the insulator layer to improve an electrical property of the insulator layer. Magnetic fields applied perpendicular to the electrode layers increase the capacitance and electrical energy storage of the insulator layer. Magnetic fields applied parallel to the electrode layers decrease the leakage current and increase the breakdown voltage of the insulator layer. The one or more ferro-magnetic elements used can include ferro-magnetic plates or magnetic nanodots. The one or more magnetized layers can be located between or outside of the electrode layers.

  • Patent number: 8149567
    Abstract: The capacitor module includes a capacitor, in which a screw hole is arranged on an outer bottom wall surface of a capacitor case housing a capacitor element, and a heat dissipater, on which a plurality of capacitor cases are fixated by screwing fixation screws in the screw holes of the capacitors. As a result, for example, the capacitor can be fixated with reliability and durability secured even under a condition where very strong vibration is continuously applied, for example, when the capacitor module is mounted on construction machinery. Further, because, an adherence of the outer bottom wall surface of the capacitor case on a fixation surface of the heat dissipater is strengthened by screwing the fixation screw in the screw hole, the capacitor can be cooled down by transferring heat produced by the capacitor to the heat dissipater as needed.
