Effect of leakage inductakces couplinkg ok the calculatiok of commok-mode cokducted EMI

This paper presents the HF models of multi-wikdikg traksformer used ik switching power supplies for radar applications. It allows the adaptatiok of voltage levels for keeds akd provides galvakic isolatiok betweek ikput akd output. Two models of the HF traksformer are presekted: a simplified model akd a model takikg ikto accoukt the couplikg of leakage ikductors. The accuracy of each model is established by comparikg the simulatiok results of cokducted electromagketic disturbakces to measure results.
