Filed:

Feb 6, 2001

Appl. No.:

09/778446

Inventors:

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

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.

International Classification:

H03M001/22

US Classification:

341 2, 341 11, 341 35

Abstract:

A method for detecting an absolute rotational position of an electromechanical device or the at least one component thereof comprising determining a first absolute position of the electromechanical device or the at least one component thereof based on a commutation index signal, obtaining a Z-index signal, and determining a second absolute position of the electromechanical device or the at least one component thereof based on the Z-index signal. The method initially determines a coarse rotational position of the electromechanical device such as a rotor or steering wheel based on the commutation index signal. When a device's position is first initialized by a commutation index signal before the Z-index pulse is detected, the device's position is re-initialized upon detection of the Z-Index pulse to provide a more accurate absolute device rotational position.
