A transformer assembly is formed from a primary winding wound about a toroidal or other annularly shaped magnetic core. A secondary winding passes through a center of the magnetic core and about an exterior of the magnetic core. The transformer assembly is disposed within a sealed enclosure into which fluid is introduced to directly contact the magnetic core before exiting through an outlet, submerging the magnetic core, the primary winding, and the secondary winding in flowing fluid. The primary winding may be disposed within a flexible tubing through which fluid flows, or alternatively, the primary winding may be cooled via contact with the cooling fluid flowing through the sealed enclosure. The secondary winding may be either internally cooled via cooling fluid flowing therethrough, or externally cooled via the cooling fluid flowing through the sealed enclosure. In some embodiments, a separate coil cooling circuit is defined external to the sealed enclosure.
