Insertion loss analysis of low voltage power line filter based on EMC standards

Abstract

This paper is intended to study Electromagnetic Compatibility (EMC) concept and filtering system as part of solution to handle Electromagnetic Interference (EMI) problems. Insertion Loss (IL) parameter from the various possible combinations were examined to choose the best performance of the new filter topology which is the most efficient. The filters installed before the equipment rectification on low voltage system (220 Volt line to neutral) is called EMI filter. EMI filters were built and analyzed from the integration of harmonic filter and Low Pass Broadband Filter (LPBF). Some EMC standards have been elaborated to determine the parameters of the filter. The results of the best performance filter were simulated by Simulink-Matlab to show that the new proposed filter can reduce power distortion and transient from switching process significantly.
