Study on modeling of high frequency power pulse transformer

Based on analyzing the physical structure and operational characteristics of high-frequency power pulse transformer, both the sub-circuit model and numerical model are presented. In the sub-circuit model, the distributed capacitances among transformer windings are reduced to concentration parameter components. It improves the practicability. In the numerical model, the piecewise modeling method is adopted because pulse transformerpsilas equivalent parameters affect the modelpsilas characteristic differently on pulsepsilas three parts, i.e. rising edge, falling edge, and action period. This method speeds up the simulation greatly. It is proved that the two models are precise and speediness, by analyzing simulation applications.
