  • Patent number: 10819117
    Abstract: Apparatuses, systems and methods for configuring and managing the combination of strings of photovoltaic energy generators to improve the energy production performance of such generators. The strings of photovoltaic energy generators are connected to terminals in a combiner box having receptacles for receiving removable modular units of various types. Removable modular units with measurement capabilities are used in the combiner boxes to measure the direct current input provided by the strings; and in light of the measurements, the removable modular units can be selectively downgraded to simpler units that do not have measurement capabilities to reduce cost, and/or selectively upgraded to more sophisticated units that can adjust the output of the respective strings, such as upconverting the output voltage of the respective strings, to improve the performance of the strings.

  • Patent number: 9942956
    Abstract: Embodiments of the invention improve efficiency and address the stability issues that arise when a boost converter is used for both backlight WLEDs and camera flash applications, which require increased voltage or output voltage less than input voltage. In prior solutions, boost converters may suffer poor efficiency when operating in a fixed high output voltage mode or may lose stability by not properly regulating their output when operating in a step-down voltage mode. To improve efficiency of the boost converter, the present invention uses a 100%-pass mode topology when the battery voltage is high enough to support the diode voltage required for the backlight WLEDs or the camera flash. On the other hand, when the battery voltage drops below the required voltage, then the converter switches automatically to boost mode to generate a sufficient output voltage to drive the diodes to the required current level.

    Abstract: The present invention provides a UPS and a DC-DC converter. An input end of the DC-DC converter is connected to a BUS+, a BUS?, and an N wire. Therefore, an input voltage is relatively low, and devices with low voltage resistance may be selected as devices in the DC-DC converter. Moreover, a load in the DC-DC converter is connected to a switch tube through a inductor rather than be directly connected to the switch tube. Therefore, a high-frequency switch wave on the second switch tube may not affect the load. Accordingly, performance of the load and an anti-electromagnetic interference capability of a whole circuit may be improved. In addition, the DC-DC converter provided in present invention does not have a structure as complicated as that of a dual BUCK topology in the prior art. Therefore, the DC-DC converter, with respect to the dual BUCK topology, has less devices and lower costs.

    Abstract: A power unit including multiple generators supplies power to a load or loads that may be variable. The generators can differ, e.g., in generating capacities, rates at which their outputs can be changed, maintenance requirements, and/or different energy-conversion efficiencies. A control unit throttles the generators independently according to a digitally implemented algorithm that may, but need not, use the difference(s) in supplying power to the load. In some cases, the controller regulates monitored power delivered to the load or loads. A power combiner is connected to the outputs of the generators. If desired, a buffer can be used between the generators and the load or loads to provide energy storage that can allow for the load or loads to change at a faster rate than the generators are throttled and for peak loads that temporarily exceed the capacity of the generators.

    Abstract: Electrical currents are detected and analyzed across structural members in a structural joint, such as a fastener of a vehicle. In some aspects, printed circuit boards etched with Rogowski coil circuits are inserted proximate the structural members in the structural joint. The Rogowski coil circuits may detect an electrical current as it flows through the structural joint. An integrator may integrate a transient current to generate an output signal, such as when the vehicle is subjected to an electrical charge. The output signal may be transmitted to an Integrated Vehicle Health Management (IVHM) system for analysis. In various aspects, the IVHM system may enable recording and reporting of various aspects of the current to enable maintenance, inspection, or real time/near real time health assessment of the vehicle.

  • Patent number: 8217626
    Abstract: The present relates to a system and method for dynamic power management of a mobile device. The mobile device has a plurality of loads and a battery charger electrically connected to a voltage rail. The method comprises monitoring the plurality of loads to determine when at least one of the loads will become active or inactive, determining a minimum required output voltage level to be provided by the voltage converter based on active loads and the at least one load that will become active or inactive and device operation; and adjusting an input voltage level via the voltage converter to provide the minimum required output voltage level on the voltage rail in advance of the at least one load becoming active or after the at least one load becomes inactive. The method further monitors the input voltage level, and determines whether the input voltage level is below a first predetermine threshold.

  • Patent number: 8207628
    Abstract: A power converter that gives priority to the high power output and only provides power to the low power output when the total potential output power is equal to or less than the rated power of the power converter. A specific power threshold is established, and when the high power output remains below this threshold for a period of time the low power output is allowed to turn on. If the high power output subsequently exceeds this threshold for a period of time, then an electronic circuit powers down the low power output in order to keep the total output power below the rated power of the power converter. Subsequently, the high power output is checked against the threshold to determine if the low power output can be turned on again. If the high power output is below the threshold, then the low power output is turned on.

  • Patent number: 8143742
    Abstract: A power distribution controller includes electronic circuitry operable to receive power and distribute power, for simultaneous consumption, to a first power load and to one or more second power loads. The electronic circuitry is also operable to monitor the amount of power consumed by the one or more second power loads, and determine whether or not the received power is or substantially is the maximum amount of power available to be received. In response to the amount of power consumed by the one or more second power loads, and the amount of received power relative to the maximum amount of power available to be received, the electronic circuitry diverts power to the first power load to cause the received power to be or substantially be the maximum amount of power available to be received.
