| Abstract: | Based on Mardiguian's noise separating network,a new network is presented for electromag-netic compatibility(EMC) analysis of power electronic noise sources.Theoretical and experimental re-search show that the new network has obvious improvement on insertion loss (IL) performance and noise rejection ability.For example,the differential mode noise IL and the maximum common mode noise rejection rationis up to about 50% and 70% ,respectively.Additionally,some applications on power elec-tronic EMC analysis of the new network are studied including influence of the load change on EMI noise of the switched mode power supply,the noise diagnosis and the suppression,and the influence of the driven circuit signal on electromagnetic interferenee(EMI) noise of the converter,etc.Results show that the new EMI noise separating network has better feasibility in conductive EMC engineering. |
| Keywords: | power electronics switched mode power supply electromagnetic compatibility (EMC) electromagnetic interferenee(EMI) noise separating network |
