    Abstract
    The development of the use of qualified rectifier is increasing, along with the more use of electronic devices with one phase DC resources, such as note book, PC computer, cellular phone, camera, , and DC drive motor. This occurs because the available resources are in the form of AC. The use of one phase rectifier which has high quality causes a serious distortion of harmonics current in the electric power line of one phase in which one phase rectifier is installed, especially in the great amount of installment. The harmonics which appear in one phase electric power line can cause the defect of electronic equipment and can disturb the function of electric equipment which is connected to the line. In order that the amount of harmonics current can be accommodated, the harmonics that appear must be in line with IEC-1000-3-2 and EN-61000-3-2 standards. Therefore, the harmonics must be reduced. One of the methods to reduce harmonics is by using RLC passive filter with band-pass filter technique which is installed on the side of AC rectifier. With the fundamental 50 Hz frequency as the center frequency, the only functions to pass the current around the fundamental frequency and does not pass the current outside the frequency band which has been set. This filter has % of harmonics reduction about 99.33% and is able to filter harmonics current from THD index 300% to 2%.
     
    Perkembangan penggunaan penyearah yang berkualitas semakin tinggi seiring dengan semakin banyak penggunaan peralatan elektronika dengan sumber daya DC satu fasa seperti note book, computer PC, hand phone, kamera,dan drive motor DC, hal ini terjadi karena sumber daya yang tersedia dalam bentuk AC. Penggunaan penyearah satu fasa berkualitas tinggi menyebabkan distorsi harmonisa arus yang serius pada saluran daya listrik satu fasa dimana penyearah satu fasa tersebut dipasang, terutama pemasangan dalam jumlah besar. Harmonisa yang timbul pada saluran daya listrik satu fasa dapat mengakibatkan kerusakan peralatan elektronika dan dapat mengganggu kerja peralatan listrik yang terhubung pada saluran tersebut. Agar besar harmonisa arus bisa diterima, harmonisa yang timbul harus sesuai dengan Standar IEC-1000-3-2 atau EN-61000-3-2. Oleh karena itu harmonisa harus direduksi. Salah satu cara mereduksi harmonisa dengan menggunakan filter pasif RLC dengan teknik bandpass filter yang dipasang pada sisi AC penyearah. Dengan frekuensi fundamental 50 Hz sebagai frekuensi centre, filter tersebut hanya melewatkan arus sekitar freuensi fundamental dan tidak melewatkan arus diluar band frekuensi yang telah diset.. Filter ini memiliki % peredaman harmonisa sekitar 99,33% dan mampu memfilter arus harmonisa dari THD sekitar 300% menjadi 2%.
