“…The amplitude and phase of the impedance Z X of the EUT can be extracted by the SP method. Then, to improve the accuracy of the SP method and determine the RLC parameters of impedance, the previous work [26] has employed the SP method in cooperation with GA and proposed a novel approach. The optimal parameter solutions obtained by GA are marked as R best , L best and C best .…”

“…However, in many other fields such as biology, environment and electrical engineering, these intelligent algorithms have been used widely [17][18][19][20][21][22][23][24][25]. To improve the defect of the traditional extraction methods, scattering parameters (SPs) in cooperation with genetic algorithm (SP-GA) method has been proposed to obtain the equivalent RCL parameters of the impedance in the previous work [26]. The SP-GA method can obtain impedance information of the EUT including amplitude, phase and equivalent RLC parameters, but data accuracy of noise source impedance can still be further optimised.…”

In this study, a new method employing scattering parameters (SPs) method, genetic algorithm (GA) and Levenberg-Marquardt algorithm (LM) is proposed for modelling conducted electromagnetic interference (EMI) noise source impedance. On the basis of the impedance information extracted by traditional SP method, GA is adopted to optimise the impedance information by taking advantage of the fast convergence speed. The obtained values of the RCL parameter are used as a set of initial values. Then, by using the advantage of the high precision of the LM, the initial values obtained by the GA are iteratively calculated. Better results can be obtained by using this combination method. This method improves the processing accuracy while ensuring the processing speed and contributes to the design of conduction EMI filter.

The performance of the artificial mains network (AMN) has an important influence on the accuracy of the conducted electromagnetic interference (EMI) noise measurement. The high‐frequency features of the AMN like impedance and voltage division factor (VDF) should be calibrated to enhance the precision of the conducted EMI noise measurement. Because the parasitic parameters of passive devices at high‐frequency have a significant influence on the performance of the AMN, a high‐frequency model of the AMN with parasitic parameters is established in the current study, and the high‐frequency parasitic parameters are extracted based on an improved differential evolution (DE) algorithm and AMN topology. The live wire impedance and VDF of R&S AMN ENV216 are obtained according to the presented approach. The results of the proposed method are compared with those extracted using the scattering parameters and a vector network analyzer, and the effectiveness of the method is validated. This study will aid in the calibration of the AMN and contribute to the accurate measurement of conducted EMI noise in electronic devices.
