International Classification:

H04M 700

US Classification:

363125, 307 66

Abstract:

Embodiments of the present invention are directed to an uninterruptible power supply for providing AC power to a load. In embodiments of the present invention, the uninterruptible power supply includes an input to receive AC power from an AC power source, an output that provides AC power, a DC voltage source that provides DC power, the DC voltage source having an energy storage device, an inverter operatively coupled to the DC voltage source to receive DC power and to provide AC power. The inverter includes first and second output nodes to provide AC power to the load, first and second input nodes to receive DC power from the DC voltage source, a resonant element having a first terminal and a second terminal, the second terminal being electrically coupled to the first output node, a first switch electrically coupled between the first terminal of the resonant element and the first input node, wherein during a first time period, the first switch is controlled to allow an electrical current path to connect the resonant element to the capacitive element, an electrical current of the path storing energy in the resonant element and charging the capacitive element to a first voltage level, and during a second time period, the first switch is controlled to block the current path to cause the stored energy in the resonant element to further charge the capacitive element to a second voltage level during the second time period. The uninterruptible power supply further includes a transfer switch constructed and arranged to select one of the AC power source and the DC voltage source as an output power source for the uninterruptible power supply.

International Classification:

H04B 10/00

US Classification:

398118, 398130, 398125

Abstract:

The systems and methods described herein allow a user to communicate using a ground sensor network that is capable of both line-of-sight (LOS) and non-line-of-sight (NLOS) communication. In particular, the systems and methods herein described transmit and receive ultraviolet radiation having a wavelength within the solar blind region from a plurality of sensing nodes arranged both in a LOS network, which communicates via LOS communication, and in a NLOS network, which communicates via NLOS communication. The ultraviolet radiation is then transmitted from the plurality of sensing nodes to a remote receiver, via LOS communication.

Assignee:

American Power Conversion Corporation - West Kingston RI

International Classification:

H02M 3/335

US Classification:

363 17, 363 98, 363132

Abstract:

At least some aspects of the invention are directed to methods and apparatus for controlling an uninterruptible power supply and subsystems of a UPS. A first aspect of the invention is directed to a method of controlling a DC-DC converter having a predetermined maximum peak load current value. The DC-DC converter has first and second outputs to couple to a load with a capacitor coupled across the first and second outputs. The method includes in a first mode of operation, charging the capacitor to a predetermined output voltage value, and in a second mode of operation, providing output current having the maximum peak load current value to a load coupled to the output of the DC-DC converter, wherein a first portion of the output current is provided by the DC-DC converter and a second portion of the output current is provided by discharging the capacitor to a voltage value that is less than the predetermined output voltage value.
