Abstract:
Systems and methods for power delivery to a load through a transfer switch are provided. The transfer switch has a first input terminal coupled to a source of a first power, a second input terminal coupled to a source of an alternate power, and an output terminal coupled to the load. A request is received from the transfer switch for the alternate power to be supplied through the transfer switch to the load. The alternate power is enabled to be supplied to the load through the transfer switch in response to the request. A power delivery system may include a first cabinet that houses a plurality of metering assemblies and a second cabinet that houses a load panel. Each metering assembly includes a power meter module that includes a power control module and a power monitor, with each power control module coupled to a corresponding transfer switch.
Abstract:
Aspects of the present disclosure involve systems, methods, and the like, for an energy interface system for interfacing alternative energy sources with a utility power source on a premises. The energy interface system provides flexibility in the use and distribution of utility energy sources and alternative energy sources based on several measurements and criteria of the interface system. For example, the energy interface system may allow for the energy consumption to adapt to changing parameters, such as utility rate schedules, cost of alternative fuels and utility premiums for consumption or generation of energy at particular times. The energy interface system also allows for deferment of charging or other high-energy loads to be recognized by the system at otherwise low-energy times. In addition, the energy interface system allows for monitoring and communication with the system for ease of configuring the system based on one or more criteria or measurements.
Abstract:
Systems and methods are provided for reliable redundant power distribution. Some embodiments include micro Automatic Transfer Switches (micro-ATSs), including various components and techniques for facilitating reliable auto-switching functionality in a small footprint (e.g., less than ten cubic inches, with at least one dimension being less than a standard NEMA rack height). Other embodiments include systems and techniques for integrating a number of micro-ATSs into a parallel auto-switching module for redundant power delivery to a number of devices. Implementations of the parallel auto-switching module are configured to be mounted in, on top of, or on the side of standard equipment racks. Still other embodiments provide power distribution topologies that exploit functionality of the micro-ATSs and/or the parallel micro-ATS modules.

A first storage system is used to store electrical power of a power source. The first storage system is connected to a first bidirectional converter by a DC power transmission system. The first bidirectional converter is connected to an AC network and the AC network is connected to a first load.
Abstract:
A power supply device includes a fuel-cell power device which supplies a direct current (DC) power to one or more load devices using fuel cells as an input source; and a control unit which controls an output from the fuel-cell power device. In the power supply device, when a load current supplied to the load device is changed, an output characteristic of the fuel-cell power device is shifted so that a rate of change in an output current of the fuel-cell power device becomes lower than a preset value. With the power supply device, even though the fuel-cell is used as a power source, a DC power supplied to the load devices can be gradually changed and therefore reduce environmental load.
Abstract:
An electric power retention distribution cell supplies stored electrical power as the primary electric supply to an end user at predetermined times. The cell has a rechargeable battery assembly, a bi-directional inverter and a switch control, and is connected to an electric utility grid, to one or more end users and to alternate power generation sources, such as wind or solar. The battery assembly is charged from the alternate power generation source and from grid power, and the cell is switched at selected times to provide the primary electric supply from stored electric power in the cell to the end user. A circuit of the battery assembly gives an extended electric power storage time by controlling storage parameters. Networks using the electric cell are also described for a utility hub network formed using two or more cells, and for a regional utility hub network formed using multiple utility hubs.
Abstract:
An exemplary power supply system includes a mains supply unit, a generator unit, a switch unit selectively connected to one of the mains supply unit and the generator unit, a heat dissipation unit connected to the switch unit, a storage unit connected to the switch unit through a control element, and a plurality of server units connected to the storage unit. The heat dissipation unit is also connected to the storage unit. When the mains supply unit is cut off, the switch unit is automatically switched to connect the generator unit with the storage unit. After the mains supply unit is cut off and before the generator unit starts to output power, the storage unit is controlled to operate to thereby energize the server units and the heat dissipation unit to work continuously.
Abstract:
Embodiments of the invention include a device and method for improved battery learn cycles for battery backup units within data storage devices. The backup unit includes a first battery pack, a corresponding charge capacity gauge, one or more second battery packs, a corresponding charge capacity gauge, and a controller switch configured to select only one battery pack for a learn cycle at any given time. The charge capacity gauges are such that, at the end of the learn cycle discharge phase, the depth of discharge of the learn cycle battery pack is such that the charge capacity of the learn cycle battery pack combined with the full charge capacity of the remaining battery packs is sufficient for the device cached data to be off-loaded to a physical data storage device, and the data storage device does not have to switch from a write-back cache mode to a write-through cache mode.

Electrical power is dynamically managed among one or more power sources and one or more loads. A plurality of monitor nodes is connected to an input terminal connected to each source, and to an output terminal connected to each load. A plurality of electrical power storage cells is connected among the input and output terminals, each cell being capable of storing power from at least one of the sources and being capable of discharging stored power to at least one of the loads. A plurality of controllable switches is connected to the cells. A programmed controller dynamically monitors operating conditions at the monitor nodes during operation of each source and each load, and selectively dynamically controls the switches to interconnect the cells in different circuit topologies in response to the monitored operating conditions.
