Several applications need high voltage and low rise time pulses that increasing of the voltage level can be done by using transformer. The rise time is increased because of transformer leakage inductance. One of the methods to decrease the rise time is using auxiliary windings between primary and secondary. In this paper, one type of pulse transformer included auxiliary windings is modeled and simulated in ANSYS software. In this study, at first the transformer has been simulated without auxiliary windings and the leakage and self inductances are obtained then the auxiliary windings are considered in the model to calculate the leakage and self inductances of the transformer. Simulation results can be used to investigate the effect of auxiliary winding on the leakage inductance.
