Analisis Kinerja LISN Pada Pengujian Conducted Emission Sesuai Standar CISPR 15

Abstract

There are 2 types of interference that can be experienced by electronic devices, one of which is conducted emission. Conducted emission is an unwanted interference signal that is acoustic (sound), electric, or electronic that occurs in the electronic device. In the conducted emission test, the Line Impedance Stabilization Network (LISN) is a tool that functions as a filter in the testing process. This study used the LISN Texbox TBLC08 50mH AC-LISN Single-Phase and the Amitec EMI-10 Single Phase, which aimed to conduct emission testing according to the CISPR 15 standard and to analyze the better EMI performance among 2 LISNs at multiple EUTs. Emissions generated in the conducted emission tests were measured under the standard parameter Average (AV) CISPR 15, on LED lamps using LISN TBLC08 at a frequency of 2.38MHz to 30MHz and Amitec LISN at a frequency of 10.2MHz-30MHz, at SMPS using LISN TBLC08 at a frequency of 647kHz to 30MHz and LISN Amitec at a frequency of 1.79MHz-30MHz, on an LED TV using LISN TBLC08 at a frequency of 647kHz to 30MHz and LISN Amitec at a frequency of 1.69MHz-30MHz.
