Low pass filter installation for reducing harmonic current emissions from LED lamps based on EMC standard

Light Emitting Diode (LED) lamp has been widely used in Indonesia for a lighting system. However, LED lamp is a nonlinear load that caused high harmonics current. This paper is focused on reducing the harmonics current that caused by LED lamp with a driver. In order to reduce the harmonic current, low pass filter is applied to the system. The experiment result revealed a significant reduction of current harmonic which is fit in with IEC 61000-3-2 class C standard and good power quality of the system.
