Abstract
In Indonesia, many LED drivers have a large Reactive Power and Small Power Factor thus not suitable with harmonic standards. It causes expensive electricity by using LED Driver on a large scale like in factory and office. LED Driver is one of the most important components in Lightning Equipment which has the greatest harmonic value for use in factory or office. A good LED driver must have power factor value more than 0.86 of small reactive power and suitable with harmonic standards. This proposed study uses Linear LED Driver using Low Pass Filter and Single Tuned Filter, which using measurement and comparison based on harmonic standard with power factor value less than 0,86. Since it has a low price, fit harmonic standard, low reactive power and high power factor. The result shows that the measurement using Single Tuned Filter PF 0,97; THDi 24,3%; Q 2.5 VAR; P 11 W and Low Pass Filter PF 0.9; THDi 23% ; Q 1.3 VAR and P 2.709 respectively.
