A three-phase magnetics assembly comprising a plurality of windings, and a unified core body is provided. The core body includes core legs which extend along central axes of the plurality of windings and around which the plurality of windings are wound such that magnetic fluxes are produced in the plurality of core legs when current flows through the plurality of windings. The plurality of windings comprise first, second, and third phase inductors, and first, second, and third phase transformers, which are positioned about the unified core body such that the core legs of the first phase inductor and second phase transformer share a central axis, the core legs of the second phase inductor and third phase transformer share a central axis, and the core legs of the third phase inductor and first phase transformer share a central axis.

Three-phase magnetics assembly

A power supply connection assembly includes a power connector for mating with a complementary connector, a first conductor electrically coupled to the power connector, a second conductor electrically coupled to the first conductor, and a third conductor electrically coupled to the second conductor. The second conductor is flexible, and the power connector is movable relative to the third conductor in at least one direction. Other example power supply connection assemblies and power supplies including one or more power supply connection assemblies are also disclosed.

Movable power connections for power supplies

An example switched-mode power supply includes an input for receiving an input voltage from a voltage source, an output for providing an output voltage to a load, and a transformer having a primary winding, a secondary winding, and a conductive shield disposed between the primary winding and the secondary winding. The power supply also includes a neutralization signal generator circuit coupled to the conductive shield to apply a neutralization signal to the conductive shield to reduce a common mode noise between the primary winding and the secondary winding of the transformer. The neutralization signal has an adjustable amplitude and/or phase. Other example power supplies and methods are also disclosed.
