Abstract
An inductor with high inductance to resistance ratio capable of handling megamp currents. Sixteen coil assemblies are radially arranged into four quadrants of four coil assemblies each and jumpers are utilized to connect the quadrants in different configurations for different inductance values. Each coil assembly is made up of a plurality of nested essentially D-shaped copper conductors collectively nested within an aluminum structural support plate in which eddy currents are minimized by a interruption in the plate. The individual conductors of each coil assembly are transposed throughout a quadrant for balanced current flow. Coil bus bars as well as an input and output bus bar are connected to predetermined ones of the coil assemblies with the input and output bus bars being connected to system input and output leads. The unit is operated at cryogenic temperatures by immersion in a liquid nitrogen filled cryostat.
