dc.description.abstractMost of the tools that used as speed control of three phase induction motors rotation is 1 phase Variable Speed Drive (VSD), where VSD is a harmonic generator. Therefore the harmonics that arise in the VSD can be reduced by using passive LC filters fasif namely passive single tuned filter that meet the standards IEC61000-3-2 Class A.The results obtained through passive LC filter could reduce the total distortion of harmonic current (THDi) from 102.9% to 23.78% while passive single tuned filter reduced the total harmonic distortion current (THDi) from 102.9% to 8.79%. At the fifth harmonics passive LC filters could reduce the harmonics current from 1.26 Ampere to 0.16 Ampere, while passive single tuned filter could reduce the harmonic current from 1.26 Amper to 0.111 Amper. The impedance produced by passive single tuned filters was smaller that is 0.436 Ω while passive LC filters was 8.34 Ω . There by passive single tuned filter is better to reduce harmonics than passive LC filters is.en_US
dc.description.abstractSebagian besar alat yang digunakan sebagai pengatur kecepatan putaran motor induksi tiga fasa adalah Variable Speed Drive (VSD) 1 fasa, di mana VSD merupakan pembangkit harmonisa. Oleh sebab itu harmonisa yang timbul pada VSD dapat direduksi dengan menggunakan filter fasif yaitu passive LC filter dan passive single tuned filter sehingga memenuhi standar IEC61000-3-2 kelas A. Hasil yang diperoleh dengan passive LC filter dapat mengurangi total distorsi harmonisa arus (THDi) dari 102,9% menjadi 23,78% sedangkan passive single tuned filter mengurangi total distorsi harmonisa arus (THDi) dari 102,9% menjadi 8,79%. Pada harmonisa ke 5 passive LC filter dapat mengurangi harmonisa dari 1,26 Amper menjadi 0,16 Amper , sedang passive single tuned filter dari 1,26 Amper menjadi 0,111 Amper. Impedansi yang dihasilkan passive single tuned filter lebih kecil yaitu 0,436 Ω sedang passive LC filter 8,34 Ω. Dengan demikian passive single tuned filter lebih baik untuk mereduksi harmonisa dibandingkan dengan passive LC filter.en_US
