  • Publication number: 20240072545
    Abstract: A DC/DC converter and a microinverter architecture using the DC/DC converter are disclosed. The DC/AC inverter is based on a differential geometry control scheme to balance and optimize the flying capacitor voltages across the flying capacitors used in the converter. Based on overall system conditions, including flying capacitor voltages, converter output voltages, input current, and input voltage, desired fields are generated. These fields are used to balance capacitor voltages such that capacitor voltage values converge, over time, to an optimal solution.

  • Publication number: 20240070628
    Abstract: This disclosure describes a vector configurator system that, as part of an inter-network facilitation system, can generate and utilize transaction vectors for facilitating network transactions among digital accounts of an inter-network facilitation system. For example, the disclosed systems can generate a transaction vector that includes a unique set of key attributes defining parameters for a network transaction and that further includes a ledger specification indicating computer code for how to execute the network transaction. Upon receiving a transaction request, the disclosed systems can access a repository of transaction vectors to determine whether a corresponding vector exists for the request. The disclosed systems can either validate or reject the transaction request based on the existence or nonexistence of a transaction vector for the request.

  • Publication number: 20240055999
    Abstract: A DC/AC inverter and microinverter architectures using the DC/AC inverter are disclosed. The DC/AC inverter is based on a differential geometry control scheme to balance and optimize the flying capacitor voltages across the flying capacitors used in the inverter's power circuit. Based on changing inverter and overall system conditions, including capacitor voltages, grid voltages, grid current, and DC bus voltages, desired fields are generated. These fields are used to balance capacitor voltages such that capacitor voltage values converge, over time, to an optimal solution.

  • Publication number: 20240055862
    Abstract: Systems and methods relating to the conversion of DC power to AC power suitable for an AC power grid. DC power is received from one or more PV panels and is converted into DC power useful for charging an energy storage subsystem. The energy storage subsystem feeds into a DC/DC converter that converts the low voltage DC power into high voltage DC power suitable for a DC/AC inverter. The DC/AC inverter then converts the high voltage DC power into AC power suitable for an AC grid. A low voltage DC/DC converter can be used that is based on a differential geometry approach such that adjustable parameter values for components within the converter converge to nominal values as system parameters evolve.

  • Publication number: 20240037086
    Abstract: This disclosure describes an account configurator system that, as part of an inter-network facilitation system, can generate account configurations for digital accounts using configuration bundles. For example, the disclosed systems can utilize custom tooling for an account configuration component that generates account configurations for digital accounts by augmenting baseline (e.g., default) product configurations with account overrides. To generate an account configuration, the disclosed systems can identify a baseline product configuration that references a configuration bundle for a subset of account configuration attributes and can modify the product configuration using an account override that also references a configuration bundle to supersede or replace one or more configuration attributes of the product configuration (with those of the configuration bundle referenced by the account override).

  • Patent number: 11863011
    Abstract: Systems and methods for controlling a plurality of DC/DC converters that are coupled to either a renewable energy source or an energy storage device. The system automatically detects the energy source coupled to the relevant DC/DC converter and operates accordingly. If the DC/DC converter is coupled to a renewable energy source (such as a PV panel), the system maximizes power extraction from the energy source. If the DC/DC converter is coupled to an energy storage device, the system performs charge/discharge functions for the attached energy storage device.

  • Publication number: 20230413126
    Abstract: The present invention provides UE mobility context creation at RIC/ORAN in 4G and 5G systems. It does this by determining a User Equipment (UE) UE is moving seamlessly from across CUs in connected mode using S1/X2/N2/Xn Handovers; downloading, by a non RT RIC, a policy to connected CUs that whenever a UE latches with initial UE message, CU sends an Identity Request to get the UEs SUPI; determining whenever the UE attaches to the CU/DU with the initial UE message, the SUPI is learnt and sent back to the Non RT RIC, along with the SUPI CU/DU and sends CRNTI, STMSI, cell information as per the use cases; allocating, by the Non RT RIC, a fresh UE ID and creating a context with parameters including Current Location, UE ID allotted by RIC, Current CRNTI, and cell information; sending, by the Non RT RIC, the fresh UE ID to the CU that the CU maintains as part of the UE context information.

  • Patent number: 11621666
    Abstract: Systems and methods for use with renewable energy resources that provide power to an energy power grid or to one or more motor loads. A control system along with an energy storage/combiner block and a DC/AC inverter is used to condition DC power received from renewable energy sources. The control system receives current and voltage outputs from the inverter along with values indicating current and voltage outputs directly from the renewable energy sources. These are then used to estimate and control motor speed when the system is in the off-grid mode. In addition, the control system uses these inputs to provide the gate pulses that are used to control the three phase AC output power from the inverter.

  • Publication number: 20230032942
    Abstract: A DC-DC power converter employs a full bridge series resonant converter topology with a resonant tank and two transformers, one before and one after the resonant tank, to obtain a high voltage (e.g., approximately 300V, approximately 1500V or greater) output from a relatively low voltage (e.g., approximately 9V-16V) input, for instance an input from one or more battery cells. DC-DC power converter is operable to output high voltage (e.g., around 300V, 1500V or higher) short duration pulses (e.g., tens of nanoseconds or less). A burst mode control technique provides as good regulation characteristics at light loads. Instead of turning OFF the active switches during an OFF period, the switches are operated at a different frequency (e.g., higher frequency) during the OFF period than a frequency at which the switches are turned ON during the ON period. Auxiliary loads can also be supplied.
