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.

Abstract
A method of operating a power delivery system that has at least one power cell includes directing air into the power cells to cool them, receiving the air from the cells, directing the air to a cooling system, and recirculating the cooled air to the power cells. Each cell may include an air intake, an air output, a water-cooled heat sink, and optionally a plurality of capacitor connectors and/or a circuit board. The air may be directed through the air intake to the air output so that air passes over the capacitor connectors and/or the circuit board before passing over the heat sink.

8. A method of operating a power delivery system having a plurality of power cells comprising:
-
providing at least one of the plurality of power cells electrically connected between a transformer and an electrical load being served; directing air into the plurality of power cells, wherein each cell comprises an air intake, an air output, a water-cooled heat sink located proximate and operably coupled to, a transistor module in a back area of the cell, and a plurality of capacitor connectors located in a front area of the cell, wherein the directing comprises directing the air through the air intake of each cell such that the air cools the capacitor connectors; passing the air over the water-cooled heat sink and the capacitor connectors of each cell so that the air passes over the capacitor connectors before passing over the heat sink; receiving the air from the power cells; cooling the received air and recirculating it to the power cells; directing water through a water intake to the heat sink of each cell and receiving water from a water output such that the water in each heat sink cools the transistor module of its associated cell; and cooling the water and recirculating it to the power cells. - View Dependent Claims (9, 10, 11, 12)
