POWER SUPPLY DEVICE FOR A HYBRID OR ELECTRIC VEHICLE

An inverter includes a plurality of pairs of power cards arranged in an array. Each pair has a proximal end and a distal end. The pairs of power cards include switches, DC inputs, DC outputs, and AC outputs. The switches are configured to convert DC power into AC power. The DC inputs are connected to the switches and extend from a first of the power cards within each pair along the distal ends. The DC outputs are connected to the switches and extend from a second of the power cards within each pair along the distal ends. The AC outputs are connected to the switches and extend from the first and the second of the power cards within each pair along the proximal ends.
