Numerical calculation of voltage distribution on pulse transformer's conical windings based on multi-conductor transmission line theory

In order to study the voltage distribution on the pulse transformer's conical windings, according to the structure of the actual pulse transformer's taper windings, the finite element model and equivalent circuit were built based on the multi-conductor transmission line theory. Using the model and circuit, the voltage distribution between the coils on the pulse was calculated. Computational results are presented to illustrate that the model can be used to calculate the voltage distribution in taper coil efficiently, which gives some references for the design of inter-turn insulation.
