Abstract
Unique methods are described to construct an inductor in the form of a tray. The basic inductor consists of a ferromagnetic core with a cavity and a completely or partially embedded winding structure. Components of a power conversion system or sub-system are mounted inside this tray structure. The terminals of the winding structure serve as mounting surfaces for components of a power conversion or other type of electronic system or sub-system. The single winding inductor is also extended to multi-winding inductors. The winding terminations are shaped to form Kelvin connections for current sensing. Flanges are added to the winding structure forming an integrated heat sink.
