“…Before such an amount of control objectives, naturally, the applications grew in variety. For instance, PWM rectifiers for motor drives were investigated when semiconductor technology advanced in terms of capabilities [6]. Also, alongside the use of a PWM rectifier, other capabilities related to power quality were explored such as voltage sag ride through [7], harmonic compensation [3], power factor compensation [8], and even fault-tolerant operation [9].…”

Controlling a PWM rectifier can be challenging due to the bilinear nature of its averaged model. This paper introduces the use of the Butterworth approach to design and control an LCL-filter-based PWM rectifier with power quality functions. By leveraging the linear part of the system, this approach reduces the number of variables involved in the control scheme. The rectifier is designed and controlled in a concatenated manner to ensure proper performance even during demanding power-quality events. The uniqueness of this approach lies in the fact that a fourth-order model can be regulated by using solely three-state variables and linear techniques founded on Butterworth polynomial synthesis. This approach differs from previous methods in that it does not employ nonlinear controllers, dq transformations, or double control loops. Hence, this divergent approach contributes to the simplification of power converter design and control through the application of the same polynomial synthesis, besides enhancing system operation in demanding scenarios. Extensive SIL simulations of a 1 kW, 220 Vrms PWM rectifier using the OPAL-RT-1400 platform were conducted to demonstrate the feasibility of the proposed controller. The selected tests reveal the validity of this proposal even when the PWM rectifier faces multiple power quality events simultaneously.

“…Rectifier circuits are used in many industrial applications such as uninterruptible power supplies [1], wind turbines [2], electric vehicle charging systems [3], DC motor control [4], active filter [5], electric locomotive [6] and STATCOM [7] applications. Depending on the usage power, single-phase rectifiers are used at low power, and three-phase rectifiers are used at high power applications [8].…”

In this study, 2.5 kW single-phase pulse-width modulated rectifier is simulated with three different control techniques to investigate the performance of controllers. Rectifier simulation is performed in Matlab / Simulink environment by using hysteresis current control, sinusoidal pulse width modulation and voltage oriented control techniques. In the performance comparison of the control techniques, considering the switching frequencies, the total harmonic content of the current drawn from the grid, the phase difference between the grid voltage and the grid current, and the DC bus voltage regulation at the output are considered as comparison criteria. The switching frequency is set to 35 kHz in sinusoidal pulse width modulation and voltage oriented control techniques. Since the switching frequency is variable in the hysteresis current control technique, the average and instantaneous switching frequency are calculated for different hysteresis band values. In the results with the technique, the switching frequency varies between 18.52 kHz and 47.6 kHz, while the average switching frequency is 34.6 kHz. As a result, the total harmonic distortion of the grid current with hysteresis current control, sinusoidal pulse width modulation and voltage oriented control techniques is 3.69%, 1.12% and 1.82%, respectively. The synchronization with the grid voltage is achieved with all techniques, and the DC voltage is regulated with active power.

“…In 2018, Gamit et al [6], used fuzzy logic instead of traditional controllers to control both DC-link voltage and current by choosing several fuzzy sets and the proposed control outperformed the above-mentioned methods by reducing the THD% value to 16%. In [7] researchers suggested a scheme of a rectifier with five levels that can be controlled by using Sine pulse width modulation SPWM technique in order to achieve a changeable speed of a DC machine with fixed load torque and low harmonic distortion in Ac supply side. The authors in [8] presented a fuzzy logic speed controller for a voltage inverter and asynchronous motor drive system.…”

This paper presents the reconfiguration of control circuit designed to control four-quadrant chopper placed in the variable speed drive system (VSDS)'s DC-link. The purpose of this design is to reduce the overall total harmonic distortion THD% of input current, and the ripple factor (RF) of the DC-link current in this system. Both of Grey Wolf Algorithm (GWO) & Particle Swarm Optimization (PSO) have been used to get the optimal parameters of proportional integral PI and proportional integral differential with filter PIDN controllers. The variable speed drive system and the proposed filter have been modeled in integration with the suggested algorithms to determine the optimal values of the controllers' parameters. The grey wolf algorithm GWO outperformed the PSO algorithm in term of reaching the optimum parameters in less number of iterations in both dynamic and static work conditions. Also, the time response of the system with GWO is better than with PSO.
