6552908, Apr 22, 2003

Filed:

Feb 19, 2002

Appl. No.:

10/078258

Inventors:

Nicholas DeNardis - Marshfield WI

Assignee:

Transpo Electronics, Inc. - Orlando FL

International Classification:

H05K 720

US Classification:

361709, 361707, 165 802, 165185, 363141, 310 68 D

Abstract:

A rectifier assembly includes two substantially identical and interchangeable heat sink plates mounted parallel to each other in spaced relation. Each heat sink plate has a plurality of identically positioned diode mounting holes. A plurality of rectifier diodes are mounted within the diode mounting holes such that plates are selectively negative or positive depending on the plurality of diodes mounted within the plate. A lead integument formed from an insulator material is mounted on a heat sink plate opposing the other heat sink plate and has embedded conductors and connectors that interconnect diode electrodes and other rectifier components.

Abstract:

A rectifier assembly includes two substantially identical and interchangeable heat sink plates mounted parallel to each other in spaced relation. Each heat sink plate has identically positioned diode mounting holes. A plurality of rectifier diodes are mounted within the diode mounting holes. Each diode has a diode electrode. One plate is selectively negative or positive depending on the plurality of diodes mounted within the plate such that one heat sink plate is negative and the other heat sink plate is positive. The diode mounting holes not receiving diodes therein provide diode electrode clearance and ventilation.

International Classification:

H02K 1100
H02M 100

US Classification:

310 68D

Abstract:

A bridge rectifier assembly includes: a self aligning cloverleaf shaped diode header which sandwiches each diode chip; a semi-circular heat and electrically conductive plate accommodated with receptacles to position the cloverleaf diodes; a heat and non-electrical conductive insulator; a finned heat and electrical conductive extrusion with similar receptacles to position the cloverleaf diodes; an articulated terminal to provide thermal and mechanical stress relief executing an electrode function adhered to the cloverleaf diode header; and a molded insulated integument with embedded electrical conductors of a cantilevered configuration to further alleviate thermodynamic and mechanical stresses. A second embodiment repeats the first embodiment, and includes a heat and electrical conductive plate that is larger in area and with the extrusion succeeded by a second plate of identical outline as the first.

International Classification:

H02P 900

US Classification:

322 28

Abstract:

A single integrated circuit for multiple vehicle voltage regulator applications is inexpensive, programmable and responsive to mixed signals. The integrated circuit provides both analog and digital functions, and uses a single voltage comparator serving all comparator functions. A variety of features are included with the single integrated circuit in order to permit the programmable, mixed signal and multiple application characteristics of the device. Among the features are the provision for a single voltage comparator that serves all comparator functions, logic gates for preventing the simultaneous activation of fixed reference divider analog switches to eliminate current transients, the use of a single TC diode for thermal shut down and multiple temperature compensation curves with different voltage versus temperature rate of change parameters, a single band gap referenced shunt regulator circuit to serve as both a power source to the integrated circuit and as a precision reference voltage for the comparator, and a selectable load control function to gradually apply the field voltage at a programmable rate consisting of reversible and "up" binary counters with associated logic to prevent abrupt torque loads on the driving engine caused by the activation of electrical loads.

Appl. No.:

6/629205

Inventors:

Nicholas F. DeNardis - Greenwood WI

International Classification:

G01R 3100
H02K 1100

US Classification:

324158MG

Abstract:

This invention relates to a circuitry for easily and quickly testing the output current capacity of a generator by connecting the generator as a controlled current source, applying to the generator's field terminals an independent voltage proportioned relative to the rated output voltage of the generator, connecting an ammeter across the output terminals of the generator, the ammeter reading being calibrated to be equal to the reciprocal of the proportioned voltage, thus providing a direct reading of output current capacity representing the full output capacity of the generator. This circuitry greatly reduces the size and cost of a holding fixture and related components to make possible a low cost generator tester.
