Abstract:
1. A method of operating a power delivery system having at least one power cell comprising: providing at least one power cell electrically connected between a transformer and an electrical load being served; providing the power cell with one or more power connectors electrically connected to a backplane of a power cell system enclosure; directing air into the power cell to cool a first area of the cell; receiving the air from the power cell, wherein the air received from the cell is warmer than the air directed into the cell; cooling the received air and recirculating it to the power cell; directing water through a water intake to a water-cooled heat sink located proximate, and operably coupled to, a transistor module in a second area of the power cell to cool the second area of the cell, the transistor module being electrically connected to the one or more power connectors of the power cell via one or more busses; receiving water from a water output, wherein water expelled through the water output is warmer than water directed into the water intake; and cooling the water and recirculating it to the power cell.
