Design of High Performance and Low Cost Line Impedance Stabilization Network for University Power Electronics and EMC Laboratories

This paper proposes how to analyze and design the line impedance stabilization network (LISN). The details are described component characteristics and how to design air coil inductors in single and multi layers based on a high self resonant frequency response concept. According to the CISPR 16-1 standard, the stabilized impedance 50 Ω of LISN at frequency range 150 kHz to 30 MHz is proved by simulation and experimental results. The proposed LISN is successful design the low cost by compare with commercial LISN. Finally, the performance of the proposed LISN is achieved comparing to CISPR standard and also with commercial LISN.
