Resistance calculation of the reusable linear magnetic flux compressor coil

The reusable linear magnetic flux compressor has been regarded as a preferred pulsed power supply for the electric gun. Some papers have discussed models for optimal design of this compressor. However, none of them have discussed the resistance calculation of the compressor coil particularly, which is the key issue of the compressor design. Based on a two-dimensional finite element model which can simulate current distributions in the conductors of the compressor coil, this paper presents a method for the resistance calculation of the compressor coil. In order to verify the proposed method, a physical model of the compressor coil has been built in the laboratory. The comparisons between the calculated and measured results show that the proposed method is an effective tool for resistance calculation of the compressor coil.
