dc.description.abstractThis thesis designs and manufactures passive LC filter to reduce harmonics at LED bulb brand B. From the test results 6 LED bulb 7 watt with brand different, LED bulb highest brand B Individual harmonic currents Harmonic Distortion (IHDi) 3rd order of 90,3 % and not in accordance with the standard IEC61000-3-2 Class C measurement data before the filter is used MATLAB/Simulink to design the parameters contained in the passive LC filter and passive filter tool making and testing a passive filter. From the results of tests performed a passive LC filter with the parameter value C = 0,562 μF, L = 13,64 H based on MATLAB / Simulink can lower order IHDi-3 becomes smaller than 90,3% to 9% reduced by 81,3% compared MATLAB simulation result becomes 13,91%. This shows the results of the draft LC passive filter can reduce harmonics at LED lamp 7watt brand B.en_US
dc.description.abstractTesis ini merancang dan membuat filter pasif LC untuk mereduksi harmonisa pada lampu LED merek B. Dari hasil pengujian 6 merek lampu LED 7 watt yang berbeda, lampu LED merek B paling tinggi arus harmonisa Individual Harmonisa Distortion (IHDi) orde-3 sebesar 90,3% dan tidak sesuai dengan standart IEC61000-3-2 Kelas C. Data hasil pengukuran sebelum filter digunakan MATLAB/Simulink untuk merancang parameter yang terdapat pada filter pasif LC dan membuat alat filter pasif serta dilakukan pengujian filter pasif. Dari hasil pengujian yang dilakukan filter pasif LC dengan nilai parameter C = 0,562μF, L = 13,64H berdasarkan MATLAB/Simulink dapat menurunkan IHDi orde-3 menjadi lebih kecil dari 90,3% menjadi 9% tereduksi sebesar 81,3% dibandingkan hasil simulasi MATLAB menjadi 13,91%. Hal ini menunjukan filter pasif LC hasil rancangan dapat menurunkan harmonisa pada lampu LED 7watt merek B.en_US
