Abstract

This paper presents the HF models of multi-winding transformer used in switching power supplies for radar applications. It allows the adaptation of voltage levels for needs and provides galvanic isolation between input and output. Two models of the HF transformer are presented: a simplified model and a model taking into account the coupling of leakage inductors. The accuracy of each model is established by comparing the simulation results of conducted electromagnetic disturbances to measure results.
