Abstract
This study aims to mitigate harmonics in single phase inverter in the design of inverter products with harmonics filters which can later be used as a basis for consideration of the quality of electricity on the harmonics side for the use of AC load power with power plants sourced from DC generators using inverter. This research was conducted at the Electrical Engineering Laboratory at State University of Jakarta.
The research method uses the experimental method. The schematic experiment starts with determining the amount of harmonics that appear both through calculations and measurements, then from the harmonic quantities designed harmonic filters to then be compared with inverter that use filters with those that do not use harmonics filters to evaluate the effectiveness of mitigation against harmonics.
The greater the non-linear load, the greater the voltage and current harmonics. To mitigate the harmonic value due to non-linear loading with a tolerance of 5% to conform with IEEE 1531-2003 standards, a non-linear load of 60 W need to be fitted with a filter of an inductor 6.705594 Henry and a capacitor 1.50121990 Micro Farad in the inverter, a non-linear load of 104 W need to be fitted with a filter of an inductor 4.680568 Henry and a capacitor 2.15045863 Micro Farad in the inverter, a non-linear load of 146 W need to be fitted with a filter of an inductor 3.523966 Henry and a capacitor 2.85603348 Micro Farad in the inverter, a non-linear load of 187 W need to be fitted with a filter of an inductor 4.012541 Henry and a capacitor 2.50837720 Micro Farad in the inverter, a non-linear load of 230 W need to be fitted with a filter of an inductor 3.455178 Henry and a capacitor 2.91347361 Micro Farad in the inverter, a non-linear load of 268 W need to be fitted with a filter of an inductor 3.071107 Henry and a capacitor 3.27678662 MIcro Farad in the inverter, a non-linear load of 311 W need to be fitted with a filter of an inductor 2.703245 Henry and a capacitor 3.72269662 Micro Farad in the inverter, a non-linear load of 351 W need to be fitted with a filter of an inductor 2.372288 Henry and a capacitor 4.24306264 Micro Farad in the inverter, a non-linear load of 390 W need to be fitted with a filter of an inductor 2.151711 Henry and a capacitor 4.67803044 Micro Farad in the inverter, a non-linear load of 429 W need to be fitted with a filter of an inductor 1.601979 Henry and a capacitor 6.28333291 Micro Farad in the inverter.
