ABSTRAKPeralatan 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.Kata kunci: PFC, flyback konverter, IEC61000-3-2, lampu LED, fuzzy type-2 ABSTRACTElectronic 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.Keywords: PFC, flyback converter, IEC61000-3-2, LED lamp, fuzzy type-2

Power Factor Correction (PFC) has become one of the most active research areas in the field of power electronics due to the surplus power required for various industrial applications around the world. In this work, a novel SEPIC converter with the Tapped Inductor model operating in Discontinuous Conduction Mode (TI-SEPIC- DCM) is proposed for PFC. The proposed TI-SEPIC-DCM improves the voltage gain through voltage multiplier cell and charge pump circuit. The voltage multiplier cell also helps in attaining the Zero-Voltage Switching (ZVS) and Zero-Current Switching (ZCS), which results in higher switching frequency and size reduction. Moreover, a third order harmonic reduction control loop has been proposed for better harmonic mitigation. The proposed work has been simulated in MATLAB and the results are obtained to validate the significance of the proposed TI-SEPIC- DCM with near unity power factor and reduced harmonics.

Beberapa tahun terakhir terjadi peningkatan kebutuhan sumber daya tegangan dc. Kebanyakan dari rangkaian elektronika daya pada sumber tegangan dc menggunakan full wave rectifier. Pemasangan nilai kapasitor yang cukup besar sebagai filter pada full wave rectifier dapat menyebabkan bentuk gelombang arus input menjadi tidak sinusoidal (terdistorsi). Perbedaan bentuk gelombang tegangan dan arus input berpengaruh pada besar kecilnya faktor daya. Interleaved Boost Converter (IBC) yang difungsikan sebagai Power Factor Correction (PFC) dengan menggunakan metode pengendali logika fuzzy diterapkan pada sistem untuk mencapai faktor daya mendekati unity. IBC bekerja pada discontinuous conduction mode (DCM). Saat rectifier menyuplai beban yang bersifat resistif maka arus input memiliki bentuk gelombang yang sefasa dengan gelombang tegangan input. Simulasi dan implementasi alat menggunakan beban yang bervariasi. Hasilnya IBC sebagai PFC dapat memperbaiki faktor daya dari 0.67 menjadi 0.93.

This paper presents a combination of power factor correction converter using Flyback converter and Full-bridge dc-dc converter in series connection. Flyback converter is operated in discontinuous conduction mode so that it can serve as a power factor correction converter and meanwhile Full-bridge dc-dc converter is used for dc regulator. This converter system is designed to produce a 86 Volt of output voltage and 2 A of output current. Both simulation and experiment results show that the power factor of this converter achieves up to 0.99 and meets harmonic standard of IEC61000-3-2.Keywords: Flyback Converter, Full-bridge DC-DC Converter, Power Factor Correction.
