Zero-dimensional modelling of helical flux compression generator in Matlab Simulink using radius matrix concept

Helical flux compression generator (HFCG) is a pulse power source that uses high explosive to convert the energy present in the explosive to the mechanical energy which is again converted to electrical pulse. In this paper a zero dimensional model is implemented in MATLAB-Simulink using the radius matrix concept which determines the radius of the armature of HFCG at each and every axial position with respect to time. This approach enables to increase the accuracy of simulation results and its analysis by increasing the number of time steps and number of axial positions. The results obtained are compared and verified with the experimental and simulation data available in literature.
