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.
