Abstract: An electrical system includes a power electronics system and a bus bar coupled to the power electronic system. The power electronics system includes a switching device configured to selectively connect and disconnect. The bus bar includes a first conductive layer and a second conductive layer. The first conductive layer is disposed directly adjacent a first insulation layer, wherein the first conductive layer is configured to conduct a first polarity of electrical power to, from, or both the power electronics system. The second conductive layer is disposed directly adjacent the first insulation layer, and is configured to conduct a second polarity of electrical power opposite the first polarity to, from, or both the power electronics system. The first conductive layer comprises a first thickness half a second thickness of the second conductive layer.

Abstract: A power generation architecture includes a plurality of photovoltaic blocks and a medium voltage direct current MVDC electrical power collector. Each photovoltaic (PV) block includes a plurality of PV groups and a combiner. Each plurality of PV groups includes a plurality of PV strings and a DC to DC power converter. Each PV string is operable to output low voltage, DC electrical power. The DC to DC power converter is operable to convert the low voltage, DC electrical power to medium voltage, DC electrical power. The combiner is operable to combine the medium voltage DC electrical power of the DC to DC power converters to produce a block output. The MVDC collector is operable to combine each block output.
