William Ziegler - Reading MA
Michael Manganese - Peabody MA
Paul A. Jordan - Wakefield MA
Mark Calvanese - Hudson MA

Assignee:

American Power Corporation - West Kingston RI

International Classification:

H02J 900

US Classification:

307 64, 361683

Abstract:

The present invention provides an uninterruptible power supply (UPS) having a chassis formed using mating panels of a sturdy, lightweight, substantially rigid material, such as ABS plastic, that are fixedly attached together to form a compact, user-friendly chassis using simple connection techniques that entail a minimum of tools and a minimal number of fastening mechanisms. In one general aspect, a UPS in accordance with the invention comprises 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, 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, and a chassis for housing at least the DC voltage source, inverter, and transfer switch. The chassis, in accordance with the invention, comprises a first panel having a substantially âLâ shaped appearance, a second panel constructed and arranged to mate to the first panel, and a first fastener securing the first panel and the second panel into a substantially fixed configuration.

Abstract:

A regenerative strobe circuit for a CMOS logic gate which only dissipates energy during the strobing of the inputs into the logic array is provided. The logic gate is connected between an output node and a first voltage source. The regenerative strobe circuit includes a first transistor (P channel) which is connected between a second voltage source and the output node, a complementary inverter having P channel transistor and N channel transistor, and second and third transistors which are respectively gate controlled by a strobe signal and a signal related to the strobe signal. The second transistor (P channel) is also connected between the second voltage source and the source of the P channel transistor of the complementary inverter. The third transistor (preferably P channel) is connected to the gate of the first transistor as well as to the source of the N channel transistor of the complementary inverter. The source of the N channel transistor of the complementary inverter is connected to said first voltage source.
