摘要： A transformer includes a core with a surface, a primary winding with two or more primary winding turns wrapped about the core, and a secondary winding with one and only one secondary winding turn extending about the core. The one and only one secondary winding turn is interleaved among the two or more primary winding turns on the surface of the core to limit magnetic flux leakage along the primary winding and the secondary winding. Power converters and power conversion methods are also described.

摘要： A Litz wire terminal assembly includes a wire bundle having a plurality of electrically conductive strands extending between a first end and a second end to define a length. Each strand includes an insulative cover having a proximate cover end at the first end and a distal cover end at the second end. The distal cover end is flush with the second end. The Litz wire terminal assembly further includes a ferrule on the wire bundle. The ferrule has a distal ferrule end at the second end of the conductive strands.

摘要： A dual-output AC-DC power converter with balanced DC output voltages is described. The DC power source has balanced DC voltage outputs relative to DC midpoint irrespective of DC load imbalance. The input to the power source is three-phase four-wire AC voltage source. Current draws from the AC three-phase voltage source have 12-pulse near sinusoidal waveform. Ripple voltage from DC positive rail to DC negative rail is 12-pulse.

摘要： A transformer assembly includes a housing with a sealed housing interior, a transformer disposed within the housing interior and having a core with windings wrapped about the core, and a condenser mounted to the housing. The condenser is in fluid communication with the housing interior. A surface of the windings bounds a coolant channel extending 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.
