“…In order to reduce the loss of rectifier bridge transmission, different topologies have been developed. Because of the unity power factor, low transmission loss, low THD, and high efficiency, bridgeless rectifiers are widely used in many applications . In addition, the bridgeless PFC topology has fewer semiconductor devices than conventional boost topology on the current path .…”

Summary In this study, a two‐stage battery charger architecture with high‐efficiency, multi‐input, and output half‐bridge LLC (HBLLC) resonance converter that performs a wide load range is proposed. The first input of the HBLLC is provided by the photovoltaic (PV) panel assembly on the vehicle. A high efficiency and fast maximum power point tracking (MPPT) algorithm has been developed for the PV panel to operate at the maximum power point. The other input is supplied by a grid‐connected AC‐DC bridgeless power factor correction (PFC) converter, which is controlled with the average current mode (ACM) control method. The most important feature that distinguishes the designed topology from previous studies is that it charges the low‐voltage battery through the PV panel. In previous studies, the low‐voltage battery was being charged via the high‐voltage battery. This allowed the high‐voltage battery to transfer power to the low‐voltage battery even when it was not charged. However, in the proposed architecture, the low‐voltage battery is fed by a PV panel. This condition allows the electric vehicle to take more miles with a single charge process. Furthermore, the proposed architecture reduces energy costs in the long term by providing some of the energy demanded from the grid. In addition, the proposed integrated battery charging circuit is intended to reduce the cost of additional cables. The system is designed as 3.1 kW power and operated under no load to full load. As for the performance of the proposed architecture, the peak efficiency of the LLC resonant converter is 95.3%. In addition, peak efficiency of the AC‐DC bridgeless PFC converter is 97.3%, while the power factor is higher than 0.99, input current total harmonic distortion (THD) is less than 5%, MPPT method accuracy is higher than 99%, and output voltage ripples (ΔV) is less than 1 V.

“…For realizing a high-performance PWM rectifier, full-order model-based controllers for the rectifier were often developed [15,24,27]. However, there will become complex if the full-order model of (3) is taken for the controller development for the high-performance SEPIC-type rectifier.…”

“…In these switched-mode PFC converters, an idea about how to achieve zero reactive power with unity power factor (UPF) in AC source line is often discussed. Two classes roughly grouped from the presented PFC schemes are as follows: (1) integration and modification in hardware circuits of power converters [1][2][3][4][5][6][7][8][9]; and (2) application of the developed control techniques to AC-to-DC or DC-to-DC converters [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The studies in [1][2][3][4][5][6][7][8][9] can be summarized as follows: in [1,2], an additional LC-diode clamper or snubber was integrated into the specified or multilevel converters so that the PFC was completed through the additional clamper or snubber.…”

Abstract:To efficiently supply wide-range DC voltage from a pulse-width modulation (PWM) rectifier, this paper presents a single-phase, full-wave, diode-bridge, single-ended primary-inductor converter-type (SEPIC-type) power-factor-correction (PFC) rectifier in continuous conduction mode with a sliding surface-regulated current-mode PWM controller. According to the switched-mode operation of the rectifier, a fourth-order switch model of the SEPIC is derived. From the fourth-order model, a simplified state-averaged model which approximately describes the dynamic behaviors of both the output voltage and inductor current is proposed. Then, from the simplified state-averaged model, the sliding surface-regulated current-mode PWM controller for the SEPIC-type PFC rectifier is proposed. The sliding surface-regulated current-mode PWM controller comprises a sliding-mode voltage controller in outer loop for robust control of the output DC-voltage and a sliding-mode current controller in inner loop for phase-synchronized control of the inductor current. For experimental studies, implementation of the proposed control algorithm in a DSP controller and a laboratory prototype of the SEPIC-type rectifier with the DSP-based PWM controller were carried out. Experimental results from the DSP controller-applied SEPIC-type rectifier are illustrated to confirm the validity of the proposed controller for practical applications.

ÖZETBu çalışmada, sürekli iletim modunda çalışan sarmaşık yapılı tek-fazlı doğrultucu için güç faktörü düzeltme kontrol yöntemlerinin detaylı analizi yapılmıştır. Sarmaşık yapılı doğrultucu devresinde oransal-integral kontrol, ortalama kayan kip kontrol ve öngörmeli akım kontrol yöntemleri kullanılarak birim güç faktörü (UPF) ve giriş akımının toplam harmonik bozulumu (THD) incelenmiştir. Sarmaşık yapılı güç faktörü düzeltici devrenin güç yoğunluğunu arttırma, giriş akım dalgacığını ve çıkış kapasitörünün etkin akımını azaltma, filtre büyüklüğünü düşürme gibi bir çok avantajı vardır. Sarmaşık yapılı dönüştürücünün 50 kHz anahtarlama frekansı ve 1kW güç değerinde benzetim ve deneysel çalışmaları gerçekleştirilmiş ve kontrol yöntemlerinin analizi yapılmıştır. Analizlerde, dönüştürücünün tüm kontrol yöntemlerinde yük değişimlerinde dayanıklı yapı sergilediği gözlenmiştir. Ayrıca, öngörmeli kontrol yönteminde işlemlerin bobin akımı ölçülmeden yapılması diğer iki kontrol yöntemine göre daha avantajlı olduğunu göstermiştir.Anahtar Kelimeler: Sarmaşık dönüştürücü, PI kontrol, Öngörmeli akım kontrol, Ortalama kayan kip kontrol PERFORMANCE ANALYSIS OF INTERLEAVED SINGLE-PHASE RECTIFIER USING DIFFERENT CURRENT CONTROL METHODS ABSTRACTIn this study, a comprehensive performance analysis of power factor correction control methods are presented for an interleaved single-phase rectifier operating under continuous conduction mode. The control of interleaved converter is achieved using proportional-integral control, average sliding control and predictive current control methods to obtain unity power factor and lower total harmonic distortion of input current. The interleaved power factor correction converters have many advantages in increasing power density, reducing input current ripple and RMS current of the boost capacitor, reducing filter volume, and cutting down the cost of materials. The analysis of the interleaved converter is presented and verified exactly by simulations and experimental carried out on 1 kW power and 50 kHz switching frequency. The performance of the current control methods for the interleaved converter is investigated by Matlab/Simulink program for different cases of operation such as change in input voltage and load. It is observed from the analysis that predictive current control method is more suitable than the others because it doesn't need sense current.
