An integrated inductive assembly includes first and second inductive elements each comprising a winding wherein winding axes of the windings are perpendicular to one another. In addition, the first and second inductive elements are carried adjacent one another by a bracket.
An electrical AC-DC power conversion system featuring 18-pulse rectification and utilizing a low weight wye-connected phase shifting autotransformer (500) supplied from a 3-phase AC source (40) through a 3-phase line reactor (41). The current harmonic distortion is less that 5% and can be further reduced to 3% level by the use of additional suppression devices (eg., chokes) which are often required in aerospace applications. The transformer (500) includes three sections (501) each spaced 120.degree. electrically apart, wherein each section (501) includes a main winding (510) and a pair of phase shift windings (540). The main winding (510) has a neutral end connected to a floating neutral point (502) and a source end (514) is connected to one phase (1, 2, 3) of the three-phase power source (40). The pair of phase shift windings (540) each include a second winding (520) and a third winding (530) connected in series and arranged to generate phase outputs (4-9) of the autotransformer (500). The above-described design results in a low weight/power configuration.
