    Abstract: Systems and methods for supplying power at a medium voltage from an uninterruptible power supply (UPS) to a load without using a transformer are disclosed. The UPS includes an energy storage device, a single stage DC-DC converter or a two-stage DC-DC converter, and a multi-level inverter, each of which are electrically coupled to a common negative bus. The DC-DC converter may include two stages in a unidirectional or bidirectional configuration. One stage of the DC-DC converter uses a flying capacitor topology. The voltages across the capacitors of the flying capacitor topology are balanced and switching losses are minimized by fixed duty cycle operation. The DC-DC converter generates a high DC voltage from a low or high voltage energy storage device such as batteries and/or ultra-capacitors. The multi-level, neutral point, diode-clamped inverter converts the high DC voltage into a medium AC voltage using a space vector pulse width modulation (SVPWM) technique. The UPS may also include a small filter to remove harmonics in the AC voltage output from the multi-level inverter.

    Abstract: Systems and methods for cooling an inverter of a variable frequency drive that drives a compressor in a cooling system for electronic equipment are disclosed. The system includes a first fluid circuit that cools electronic equipment using a first fluid flowing therethrough and a second fluid circuit that free cools a second fluid flowing therethrough. The second fluid circuit cools the first fluid using the free-cooled second fluid. The system further includes a third fluid circuit that mechanically cools the second fluid using a third fluid flowing therethrough as a function of the wet bulb temperature of atmospheric air. The third fluid circuit includes at least one compressor compresses the third fluid and is driven by a motor coupled to the variable frequency drive. At least a portion of the first fluid flowing through the third fluid circuit is diverted to cool the inverter of the variable frequency drive.

    Abstract: A power distribution system for data center systems (and corresponding method) feeds DC power directly to a first AC-DC power supply of a computer system in the data center system and feeds AC power to a second AC-DC power supply of the computer system to efficiently and reliably provide an uninterruptible supply of power to the computer system. The power distribution system includes an energy storage unit for supplying the DC power, a charger for charging the energy storage unit, and an inverter through which the energy storage unit provides energy to an electrical substation of an electrical grid. The charger is configured to receive energy from a renewable energy source and the electrical substation. The inverter may also be configured to receive renewable energy from the renewable energy source and supply that energy to the electrical substation. An uninterruptible power supply may be coupled between the electrical substation and the AC power feed. The power distribution system further includes a monitor for monitoring the flow of current to and/or from the electrical substation, a communications interface for receiving messages or requests from a utility company associated with the electrical substation, and a controller for controlling the components of the power distribution system based on requests from the utility company and the information gathered by the monitor.

    Abstract: An air curtain containment system and assembly for data centers forms an air curtain over the server cabinets thereby separating hot air in a hot aisle from cool ambient air. The air curtain containment system includes ducts which include a hot air intake section that receives hot air discharged from servers, which are disposed in server cabinets. The ducts include heat exchangers for cooling the hot air and at least one air curtain discharge section. A housing is coupled to a wall of the ducts, and includes a cooling edge device fan. The cooling edge device fan is disposed along the ducts, and is configured to draw the hot air for cooling through the heat exchangers. An air curtain fan assembly is disposed along the ducts. The air curtain fan assembly expels cold air through the air curtain discharge section, and thereby forms an air curtain over the server cabinets.
