Abstract
In an embodiment, a drive system includes a transformer enclosed in an enclosure including a heat exchanger to cool a fluid medium. In addition, the system includes a plurality of power cubes each including a rectifier, a DC-link, and an inverter. Each power cube may include 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. In turn, a manifold assembly is to couple at least the power cubes to enable two phase cooling of the power cubes and the transformer via one or more heat exchangers.
