Laboratory Line Impedance Stabilisation Network: Experimental studies

In this paper we have completed experimental studies about a measurement device of electromagnetic conducted noise emission generated by Power Electronics (converters). This equipment, manufactured in Electromagnetic Systems Laboratory (ESL) of EMP, is called a Line Impedance Stabilization Network (LISN). Firstly, a presentation of the two topologies: mono and double cells are highlighted. Afterwards, we have experienced its performances by experimental test benches. The performance tests concern the Voltage Drop (VD) caused between the inputs and outputs LISN, on the other hand, they concern as well a Fidelity Test (FT) operated on this equipment. Once the LISN has been manufactured in laboratory, we have tested its output impedance (characteristic impedance) which has to be constant (50Ω) around frequency range (150 kHz–30 MHz) limited by CISPR regulations.
