-Wind energy conversion systems (WECS) which consist of wind turbines with permanent magnet synchronous generator (PMSG) and full-power converters have become widespread in the field of renewable power systems. Generally, conventional diode bridge rectifiers have used to obtain a constant DC bus voltage from output of PMSG based wind generator. In recent years, together advanced power electronics technology, Pulse Width Modulation (PWM) rectifiers have used in WECS. PWM rectifiers are used in many applications thanks to their characteristics such as high power factor and low harmonic distortion. In general, L, LC and LCL-type filter configurations are used in these rectifiers. These filter configurations are not exactly compensate current and voltage harmonics. This study proposes a hybrid passive filter configuration for PWM rectifiers instead of existing filters. The performance of hybrid passive filter was tested via MATLAB/Simulink environment under various operational conditions and was compared with LCL filter structure. In addition, neuro-fuzzy controller (NFC) was preferred to increase the performance of PWM rectifier in DC bus voltage control against disturbances because of its robust and nonlinear structure. The study demonstrates that the hybrid passive filter configuration proposed in this study successfully compensates current and voltage harmonics, and improves total harmonic distortion and true power factor.

“…Fuzzy mode controllers proposed in [9] and [10] are robust, but the accuracy and performance of the controller is highly dependent on the selection of number of fuzzy variables and fuzzy logic rule base. The real-time implementation of the controller is limited due to its tedious fuzzy rule tuning and its need for significant computational resources.…”

Direct Power based Sliding Mode (DPSMC) control for controlling single phase AC-DC pre regulator assuring unity power factor and stable output voltage under load variation is proposed in this paper. Direct Power Based Control (DPC) commonly applied for three phase circuits, is combined with Sliding mode control (SMC) to control and regulate the single-phase AC-DC pre regulator. The proposed DPSMC apart from being simple to design and robust to parameter variations also helps in reducing the line current distortion inherent to AC-DC Converters. The design of the proposed power based sliding mode control along with its existence condition is discussed. The performance of the proposed method over conventional sliding mode control is assessed through computer simulations and the feasibility of the proposed controller is confirmed through experimental implementation carried out with the help of LabVIEW and sbRIO FPGA development board.

“…During the past twenty years, numerous publications on the development of power-factorcorrection (PFC) pulse-width modulation (PWM) AC-to-DC converters have been published [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. 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.…”

“…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.
