【正文】 ea around of an interference source or by conduction through mon cabling or wiring connections. In this study conducted emission is considered only. Equipment such as puters, receivers, amplifiers, industrial controllers, etc that are exposed to interference corruption are called victims. The mon connections of elements, source lines and cabling provide paths for conducted noise or interference. Electromagic conducted interference has two ponents as differential mode and mon mode ??9 . A. Differential mode conducted interference This mode is related to the noise that is imposed between different lines of a test circuit by a noise source. Related current path is shown in Fig. 1 ??9 . The interference source, path impedances, differential mode current and load impedance are also shown in Fig. 1. B. Common mode conducted interference Common mode noise or interference could appear and impose between the lines, cables or connections and mon ground. Any leakage current between load and mon ground could be modeled by interference voltage source. Fig. 2 demonstrates the mon mode interference source, mon mode currents Icm1 and Icm2 and the related current paths??9 . The power electronics converters perform as noise source between lines of the supply work. In this study differential mode of conducted interference is particularly important and discussion will be continued considering this mode only. III. ELECTROMAGNETIC COMPATIBILITY REGULATIONS Application of electrical equipment especially static power electronic converters in different equipment is increasing more and more. As mentioned before, powe
