1. A transformer assembly, comprising:
a housing with a sealed housing interior;
a transformer disposed within the housing interior and having:
a magnetic core;
a slotted bobbin seated about the magnetic core and having slot surfaces; and
windings wrapped about the core and having core-facing surfaces, wherein the winding core-facing surfaces and bobbin slot surfaces are spaced apart by a coolant channel; and
a condenser mounted to the housing in fluid communication with the housing interior,
wherein the coolant channel extends along a height of the bobbin between the windings and the condenser to convey coolant of a first phase to the condenser and receive coolant of a second phase from the condenser.
