6822850, Nov 23, 2004

Filed:

Jun 5, 2003

Appl. No.:

10/455673

Inventors:

David W. Pfeifer - PepperPike OH
John M. Kasunich - Mayfield Heights OH
Richard Sheppard - Mentor OH

Assignee:

Rockwell Automation Technologies, Inc. - Mayfield Heights OH

International Classification:

H02B 120

US Classification:

361611, 361637, 363144, 174 72 B

Abstract:

An apparatus for linking together power switching devices having intra-converter connection terminals to form a power conversion assembly, the apparatus comprising a planar bus bar including positive and negative DC bus layers and insulating layers that insulate each of the DC bus layers, the bar also including at least a first external insulating layer that forms a first external surface of the bar, the bar also forming at least first and second linking edges and first and second pluralities of linkages formed along the first and second linking edges, respectively, each linkage linked to one of the positive and negative DC bus layers and configured to be linkable to at least one of the power switching device intra-converter connection terminals, in some cases positive and negative DC bus linkages are also provided to render the conversion assembly extremely versatile.

Assignee:

Rockwell Automation Technologies, Inc. - Mayfield Heights OH

International Classification:

H05K 7/20

US Classification:

361699, 361707, 361719, 165 804, 16510433, 174 151

Abstract:

An electronic converter assembly including a liquid cooled heat sink member having a sink length dimension, at least one mounting surface and first and second oppositely facing lateral surfaces, the mounting surface and first and second lateral surfaces forming first and second lateral edges, respectively, the sink member also forming at least one internal channel that extends substantially along the entire sink length, an inlet and an outlet that open into opposite ends of the channel, a plurality of power switching devices mounted side by side to the mounting surface thereby forming a single device row that extends substantially along the sink length, each device including intra-converter terminals that are substantially within a single connection plane, a plurality of capacitors, each capacitor including capacitor connection terminals, the capacitors linked for support to and adjacent the sink member with the capacitor terminals juxtaposed substantially within the connection plane and a linkage assembly including a plurality of conductors that link the capacitor terminals to the intra-converter terminals to form a power conversion topology.
