Providing a cooling system for a medium voltage drive system

摘要

In an embodiment, a medium voltage drive system includes a transformer, multiple power cubes each coupled to the transformer, and a manifold assembly. Each power cube includes cold plates each coupled to a corresponding switching device of the cube, an inlet port in communication with a first one of the cold plates and an outlet port in communication with a last one of the cold plates. The manifold assembly can support an inlet conduit and an outlet conduit and further support first and second connection members to enable blind mating of each of the first connection members to the inlet port of one of the power cubes and each of the second connection members to the outlet port of one of the power cubes to enable two phase cooling of the plurality of power cubes.
