In space, power-supply subsystems are needed that have high power-processing densities and low product profiles. New core and winding geometries for the magnetic components of these subsystems have been developed to match the specifications for use in space. These innovations include the use of both rigid and flexible printed-circuit methods for windings, matrix arrays of miniature toroidal cores, as well as various "flattened" magnetic core shapes. Another proven technique to reduce the volume and weight of the magnetic content of power converters is the design art of integrated-magnetics. with this design, only one magnetic core structure is needed for a multiplicity of transformer and inductive functions of a power converter circuit. The goal of this project is to develop new methods so that planar-magnetic design concepts can be blended and extended with integrated- magnetic design approaches to obtain superior magnetic components for power applications. The project will also make and test sample magnetic components to verify the design methods.
Potential Commercial Applications:Applications are possible in any electronic power-processing product requiring low-profile, cost-effective, and high-density power magnetic components such as an AC-DC or DC-DC power supply.
