  • Patent number: 10186898
    Abstract: A capacitive power system having a service life extending approach. The system may have an ultra or super capacitor with high capacitance. A predetermined amount of energy may be stored in the capacitor, sufficient for providing power to an electrically powered mechanism in the event the mechanism loses its power, to place it in a fail safe condition. With the capacitor at an initial capacitance, the working voltage may be set as low as possible while still retaining sufficient capacity for storing the predetermined amount of energy. As the capacitor's capacitance decreases with age, the working voltage of the capacitor may be gradually increased to compensate for lost capacitance. If the mechanism loses power, then a discharge of the capacitor may be initiated to transfer energy to the mechanism. If the electrical mechanism has power, then a charging of the capacitor may be initiated to transfer energy to the capacitor.

  • Patent number: 10181722
    Abstract: A single-inductor DC-DC converter generates two DC output voltages at two capacitors. The converter selectively transfers energy from a battery to the inductor or from the inductor to a selected capacitor. While the converter is still settling, the converter is regulated based on only the more deficient DC output voltage. After the converter has already settled, the converter is regulated based on the common-mode voltage for both DC output voltages. By regulating the still-settling converter based on only the more deficient DC output voltage, instead of the common-mode voltage, even greater deficiencies in that already more-deficient DC output voltage are avoided.
