Simulation research on feed modes of linear transformer driver

Feed modes affect the parameters of and wave propagation in the linear transformer, while a water dielectric pulse forming line is used to feed the primary coil of the transformer to develop a pulsed driver. With the help of Maxwell software, simulation research on different feed modes was done from a standpoint of field uniformity. Simulation results show that, the current density in the primary coil of a unilateral fed linear transformer distributes non-uniformly, the magnetizing inductance is much larger than ideal values calculated by equivalent formulas, and their ratio, namely, current density magnification coefficient has little influence on the coupling coefficient of the transformer. Tetrahedral feed produces more uniform field but with high cost and complexity. Thus bilateral fee
