Abstract:
Electromagnetic interference ( EM I) is one of important issues in electromagnetic compatibility( EMC) engi neering and how EM I noise measurement is done will directly affects the noise supp ression results. In this paper an imp roved EM I noise solution scheme is p roposed that differs on p resenting an intellectual and unified idea to make noise independent componentmeasurement in conjunction with noise analysis and noise supp ression. The p rincip le of independent componentmeasurement and intellectual noise p rocessing software are studied. Also noise characteriza-tion andmode analysis are imp lemented for noise mitigation and future EMC solution scheme. Moreover, EMC experiment for switched reluctance motor ( SRM) drive system is conducted to show the efficiency of new method developed in this paper.
