Providing a cooling system for a medium voltage drive system

A medium voltage drive system comprising:

• at least one transformer having at least one primary winding to receive power from a utility connection and at least one secondary winding;
• a plurality of power cubes each coupled to the at least one secondary winding and including a rectifier, a DC-link, and an inverter, wherein each power cube includes a plurality of cold plates each coupled to a corresponding switching device of the inverter, an inlet port in communication with a first one of the plurality of cold plates and an outlet port in communication with a last one of the plurality of cold plates;
• and
• a manifold assembly to support an inlet conduit and an outlet conduit and further to support a plurality of first connection members and a plurality of second connection members to enable blind mating of each of the plurality of first connection members to the inlet port of one of the plurality of power cubes and each of the plurality of second connection members to the outlet port of one of the plurality of power cubes to enable two phase cooling of the plurality of power cubes.
