Simone Negri received the B.Sc. and M.Sc. (cum Laude) and PhD (cum Laude) degrees in Electrical Engineering from Politecnico di Milano, Milan, Italy, in 2014, 2016, and 2020, respectively. He is currently an Assistant Professor with Department of the Electronics, Information and Bioengineering (DEIB), Politecnico di Milano, where he has been a Postdoctoral Research Fellow from 2019 to 2022. He authored over 40 papers in international journals and conference proceedings.
His main research interests are in the field of Electromagnetic Compatibility (EMC), and include: a) development of innovative methods and experimental setups for the identification of the relevant parameters of single components and multiport devices up to 110 MHz, with particular attention to non-intrusive methods for the characterization of energized systems; b) development of physical and black-box (behavioural) EMI filter models for attenuation prediction and assessment in standard and non-standard conditions, including operation in non-linear circuits, trough frequency-domain and time-domain simulations; c) development of behavioural models for intentional and unintentional EMI sources, including power converters and PLC systems, aimed at prediction of conducted emissions levels and prevention of interference issues. Further research interests include power converters modelling and control, application of advanced control and optimization techniques in power systems, hybrid AC/DC distribution systems, and power quality and reliability. He has participated in research projects funded by ST Microelectronics, Italian Ministry of Defence (NAVARM), ABB, and Schurter Electronic Components, and he has been involved in teaching activities held by Politecnico di Milano and Orders of Engineers.
Dr. Negri is the recipient of the 2023 International Union of Radio Science (URSI) “Roberto Sorrentino” Young Scientist Best Paper Award, received the National Scientific Qualification as Associate Professor of Electrical Engineering from Italian Ministry of University and Research in 2025. He is a Senior Member of the IEEE and is active in the standardization of LVDC system as Member of the CEI (Italian Electrotechnical Committee) CT 99 and CT 320 technical committees, where he is the convenor of the working group GdL1, Member of the IEC SyC LVDC working group WG3 – Parameters for protection and safety in DC and TC73 WG 73-235-NP – DC Short circuit calculation, and Member of the European Commission Set Plan Implementation Working Group on Direct Current Technologies.
Talk: Non-intrusive Characterization Methods for Multiport Electrical Devices
Abstract:
Non-intrusive characterization methods based on inductive probes clamped on power cables are appreciated as the measurements can be carried out while the system under test is operating. These benefits are particularly relevant for EMC analysis, as radio-frequency instrumentation cannot withstand the typical voltage and current levels of electric power systems.
Most non-intrusive impedance measurement methods provide excellent accuracy, but are limited to one-port measurements. This feature strongly limits their applicability to the several modern EMC problems, such as the EMC analysis of three-phase power electronics converters commonly used for electrical drives, renewable energy, and automotive applications, or bipolar DC converters commonly used in low voltage DC applications.
This talk provides a brief overview of the state of the art of one-port non-intrusive impedance measurement methods, and successively focuses on recent research advancements on the characterization of multiport electrical devices. Specifically, multiport electrical devices can be properly represented by impedance or admittance matrix representations, including mutual parameters, which require a specific measurement setup involving multiple probes. The talk presents the theoretical foundation of the non-intrusive characterization of multiport electrical devices, discusses the considered setup, instrumentation, and probe requirements, and presents a number of applicative examples including the characterization of power electronic converters in terms of physical and modal impedances and admittances.
