Numerical Analysis of Conductor Response to Fast-Rising High-Current Pulses

Abstract

A computer code has been developed to rapidly evaluate the response of a collection of conductors of arbitrary geometry to a fast-rising, high-current pulsed discharge. The code applies to any set of conductors which are long compared to their transverse dimensions (2-D limit). The high frequency diffusion limited current distribution is evaluated to determine the high frequency inductance and resistance, the surface temperature rise and the local magnetic stress and total force on each conductor for a specified peak current. The model has been validated against analytic solutions for simple geometries and experimental results for more intricate geometries. The code is optimized for fast computation, facilitating an iterative design procedure for arbitrary conductor assemblies.
