    Abstract: A power distribution and communication system includes nodes connected by power lines and communication links. The system receives power from one or more power sources. Each node contains at least one power port, data port and load port. Associated with each power port and load port is a port monitor for measuring current flowing into or out of the port and the voltage difference between the port outlet and ground, which measurements are passed to a processing element. The processing element and monitor analyze measured values to detect fault conditions. Upon fault condition detection, the port is disabled by opening a switch, disconnecting the port from the system voltage. The processing element receives power directly from the power line, thus receiving power from a live power line even if the associated power port is disabled allowing the processing element to enable a disabled node following a failure.

  • Patent number: 9991738
    Abstract: One or more techniques and/or systems are provided for providing power to a plurality of dispensers. For example, a supply coupler, such as an alternating current to direct current power converter, is coupled to an energy storage component and/or a load coupler of a power distribution apparatus. The supply coupler provides power over the load coupler to one or more dispensers for operation. The supply coupler provides power to the energy storage component for energy storage. Responsive to a load on the power distribution apparatus exceeding a supply current of the power provided by the supply coupler (e.g., multiple dispensers may attempt to perform concurrent dispense events), the energy storage component may discharge energy to provide additional power to one or more dispensers to facilitate concurrent dispense events. Because the power distribution apparatus may connect to multiple dispensers, a cord management device may be used for power cord management.

    Abstract: An electrical power source includes a power converter and either an electrical generator or an electrical energy storage device. Power flow is controlled through control of the power converter based on a voltage source and resistance model of the electrical power source. A power converter for an electrical generator is controlled to synthesize a constant voltage of the voltage source and a variable value of the resistance. The resistance value is controlled to deliver a maximum available output power to the electrical microgrid over a range of microgrid voltages up to a voltage below a maximum allowable voltage of the electrical microgrid. For an electrical energy storage device, the power converter is controlled to synthesize a resistance value of the resistance that is dependent upon a phase angle between the voltage at the microgrid side of the electrical power source and current of the electrical energy storage device.

  • Patent number: 9595827
    Abstract: A subsystem is configured to apply a voltage source to a gated circuit domain in a manner that limits in-rush current and affords minimal time delay. A control signal turns on a wake-up switch that connects the voltage source to the domain. The equivalent series resistance of the wake-up switch has a magnitude that limits the transient charge current to the gated domain. A digital control circuit monitors the resulting rising domain voltage and determines when the domain voltage reaches operating level, at which point additional transient current will be minimal. The control circuit then activates a primary switch that connects the voltage source to the domain through a series resistance of negligible magnitude. An adjustment element provides the option to permanently set a control signal that marginally reduces the time at which the control circuit activates the primary switch to compensate for variations in circuit parameters.

  • Patent number: 9588563
    Abstract: A host device can manage a controllable power adapter accessory using a communication protocol. Based on information provided by the controllable power adapter accessory as to its power capabilities and the power needs and preferences of the host device, the host device can determine a desired power profile and request power from the accessory conforming to the desired profile. The desired power profile can also depend in part on the power-carrying capability of one or more cables connected between the host device and the accessory. In some instances, the host device and controllable power adapter accessory can be connected via an intermediary accessory that can siphon power from the controllable power adapter accessory, and the host device can manage the power siphoning behavior of the intermediary accessory using the communication protocol.

  • Patent number: 9280405
    Abstract: A powerline communication (PLC) power supply and modem interface can be implemented using a power supply processing unit coupled with a PLC modem unit. The power supply processing unit generates a composite PLC signal comprising a PLC signal and a DC power signal modulated with a zero cross signal (all determined from an AC powerline signal). High-powered components of the PLC modem unit can cause signal distortion in the zero cross signal component of the composite PLC signal making it difficult to extract zero cross information. An error correction unit can be implemented at the PLC modem unit to minimize the signal distortion and generate a zero cross signal with little or no error. The PLC modem unit also extracts the PLC signal and the DC power signal from the composite PLC signal, and processes the PLC signal using the zero cross information extracted from the corrected zero cross signal.
