ABSTRAK

Peralatan elektronika umumnya memerlukan catu daya berupa sumber tegangan DC yang berasal dari sumber tegangan AC 220 V yang disearahkan menggunakan penyearah gelombang penuh. Pemasangan filter kapasitor pada sisi output penyearah menyebabkan bentuk gelombang arus masukan terdistorsi sehingga menimbulkan arus harmonisa yang mengakibatkan nilai faktor daya menjadi rendah. Artikel ini membahas mengenai paralel flyback konverter sebagai PFC (Power Factor Correction) pada lampu LED 36 V/60 W menggunakan algoritma fuzzy type-2. Flyback konverter pertama sebagai regulator tegangan DC bekerja dalam kondisi CCM (Continuous Conduction Mode). Flyback konverter kedua sebagai PFC bekerja dalam kondisi DCM (Discontinuous Conduction Mode) sehingga konverter bersifat resistif. Hasil simulasi menunjukkan bahwa paralel flyback konverter dapat memperbaiki faktor daya dari 0.597 menjadi 0.903 dan dapat menjaga tegangan keluaran konstan sebesar 36 V menggunakan algoritma fuzzy type-2 serta arus input yang dihasilkan memenuhi standar internasional hamonisa IEC61000-3-2 kelas C.

ABSTRACT

Electronic equipment generally requires a DC voltage source that comes from a rectified 220 AC voltage source using full-wave rectifier. Installing capacitor filter on the output of rectifier makes the input current waveform becoming distorted that cause harmonic current which results in low power factor value. This article discusses parallel flyback converter as PFC (Power Factor Correction) on 36 V/60 W LED lamp using fuzzy type-2 algorithm. The first flyback converter as voltage dc regulator works in CCM (Continuous Conduction Mode). The second flyback converter as PFC works in DCM (Discontinuous Conduction Mode) to make the resistive converter. The simulation results shows the parallel flyback converter can improve the power factor from 0.597 to become 0.903 and can maintain a constant output voltage of 36 V using fuzzy type-2 algorithm and the input current meets the international harmonics standard of IEC61000-3-2 class C.
