ABSTRACT:
An improved transformer (20) and method of transformer construction. Primary and secondary windings (30 and 32) are spirally wound onto a spherically shaped core member (24). The core is preferably of laminated construction and can be of either planar or radial configuration. A flux intensifier shield member (40) defines an inner spherical cavity (Y) sized to cooperatively overlie and substantially enclose the inner core and winding assembly. The shield may comprise a pair of hemispherically shaped members including radially extending leaf-like vanes (46) that enable and enhance cooling of the core assembly as well as providing improved transformer efficiency and protective shielding of the core assembly.
