Laminated bus bar for use with a power conversion configuration
First Claim
1. 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.
