Accurate Finite Element Simulation of Conductors

Simulation of electromagnetic systems relies on the accurate and efficient representation of electrical conductors and coils. This whitepaper reviews the ways conductors can be represented using the industry leading Opera Simulation Software Suite from Cobham. The methods explored include various bulk approximations useful for multi-turn windings as well as explicit methods to include current redistribution due to proximity, geometry and skin effects.

Magnetics Design: Specification, Performance & Economics

An informative white paper from Datatronics Romoland, Inc., provides a discussion of the design, development and delivery of affordable magnetic components. The design development process begins once performance requirements are specified. Upon design approval, the procurement of materials for a prototype build is initiated. During this stage, specifications are not final and options remain open for cost-effective production. Specifications must be reviewed and design trade-offs evaluated to ensure that the technical requirements are economically attainable with consideration given to performance and tolerance in relation to affordable cost.

Step on It! Walking for Power

What would be an alternative energy resource that could work well in the middle of a crowded city? The answer was a technology that harvests mechanical energy of walking feet and converts it to electrical energy via a special floor tile. But it was a big step from theory to practical design.
