Abstract

To realize the efficient analysis of the long cable bundle terminated with non-linear loads

combining equivalent cable bundle method（ECBM） with simulation program with integrated circuit emphasis（SPICE） model method

we put forward a more reduced SPICE model. The equivalent steps of equivalent cable bundle method was adjusted

ECBM was developed

and the reduced method of nonlinear loads was presented. The results show that computational accuracy is reliable for electromagnetic pulse（EMP） coupling to a 2 m length cable bundle with four cores. and they are in good agreement. The reduced times are 0.64 s

0.98 s

and 1.23 s for linear loads

non-linear loads T15KE39 CA

and non-linear loads B32K130

respectively. Computational efficiency is greatly improved by above 60%. The results provide a guidance for the EMP analysis of the long cable bundle loaded by non-linear loads.
