REDUCTION OF CURRENT HARMONIC CAUSED BY AC-DC RECTIFICATION WITH HYBRID FILTER FOR ENERGY SAVING LAMP ELECTRONIC BALLAST
ABSTRACT: Use LHE (Energy
Saving Lamp) that use electronic ballasts
will cause harmonics, both current and voltage harmonics and the harmonics will
result in a poor electric power quality. On the
other hand LHE
that uses electronic
ballasts have good
properties in converting
electrical energy into light,
because it has
an efficiency of
above 80%. This
research aims to
analyze the activity electric
power quality in the distribution network due to load LHE with electronic
ballast. We then measured with a
laboratory scale and continued
analysis using the program, for the issues
analyzed include: the
use of electronic
ballasts will cause
harmonic currents and
voltage, harmonics and odd harmonics influential 3rd harmonic dominant,
harmonics will affect the quality of electric
power. thus will
follow up effort
to minimize the
presence of harmonics
in particular harmonic currents
and harmonic influence
further analyzed for
capacity LHE group
with large-capacity load on the
distribution network. In order
to save electrical
energy, mainly for
lighting, energy-saving lamps
can be used. Those
lamps, which use
electronic ballast and
added by hybrid
filter, can reduce
negative effect due to harmonic,
so that efficient condition in load and optimal condition in distribution
network can be obtained. This
study was carried
out by a
simulation with PSIM
program version 9.0
and a reference to
minimize current harmonics
in such energy-saving
lamps using electronic
ballast to increase the quality
of electrical power. Results of the study show that reduction in large current
harmonics of 10% due to AC-DC rectification was because of electronic ballast
use. Moreover, some efforts were found reducing the harmonic effect by using
hybrid filter to meet the standards of IEC 61000-3-2 in Class C.
