An Conducted Electromagnetic Interference (EMI) Noise Source Modeling Method Using Hilbert Transform
In this paper an approach for power-line EMI (electromagnetic interference) noise source modeling is presented by using Hilbert transform,. First,the importance on EMI noise source modeling.,i.e. the source impedance extraction is introduced as the fundamental of power-line EMI filter design for conducted EMI noise suppression. Next,the approach is described and analyzed where the insertion loss method is applied for source impedance amplitude extraction and Hilbert transform method is employed for impedance phase extraction. Simulation and experimental results show that this approach can be utilized effectively for conducted EM! noise source modeling.
