Active front-end boost rectifiers can replace the uncontrolled diode bridge rectifiers for ac-dc conversion offering high power quality with near unity power factor. The four-switch, B4, topology is gaining interest, either as an inverter or a rectifier, where each switch should withstand the full dc link voltage. Higher voltage-rated power semiconductor devices not only imply slower response with lower overall efficiency but also higher cost and size. Thus, multilevel inverters become a viable solution. This paper investigates a two-leg neutral-point diode-clamped B8 rectifier allowing the series connection of fast, efficient, and low voltage rating switches. The proposed rectifier has better performance and efficiency than the B4 rectifier. Only two inductors instead of three are required. Model predictive current control (MPCC) is developed for accurate current tracking. A model of the proposed rectifier is detailed for the implementation of MPCC. The concept is validated by simulation and experimentation.

“…Multi-pulse transformer-based rectifiers like 12, 18 and 24 pulses rectifiers, can reduce the THD [8]. It is reported that THD is in the range of 15% using a 12-pulse rectifier [9]. However, its bulky structure makes it a less favorable choice.…”

“…Recently, modular power converters with AFE rectifiers have been extensively utilized by motor drives to improve their harmonic characteristics and raise the overall power quality. In [13], a modular AFE rectifier with a common DC link is extended for multidrive configuration to mitigate harmonic distortions based on the electronic phase shifting technique. To elevate the modular AFE rectifier behavior, it is useful to separate the rectifier module from the drive unit and consider it as the main interface circuit between the AC power grid and the motor drive system's DC link and deploy a robust and feasible control strategy.…”

Active front-end (AFE) rectifiers have become widely employed in power systems to achieve unity power factor and harmonic mitigations. The typical modeling approaches applied for AFE rectifiers in the literature mostly relied on two baselines: the detailed model and the time-average model. The former approach deals with the switching element model (SEM), which leads to significant harmonics in currents with distorted waveforms. The latter approach uses the average-value model (AVM) to overcome the currents’ harmonics as well as provide fast responses. However, even the AVM baseline has shown problems during the starting stage (lack of control signals) and over the dead-time periods, which causes serious issues in the implementation process. This paper presents an improved dynamic AVM for AFE rectifiers by precisely considering the issues mentioned above, along with the practical starting procedure and desirable initialization. The studied AFE rectifier is developed using the voltage-oriented control (VOC) technique based on the different modeling methodologies, including SEM, Conventional AVM, and the proposed AVM. The performance of all models is analyzed and compared using simulation results with MATLAB/Simulink R2023a Function blocks for all the algorithm parts and SimScape elements for the electrical circuit model. The simulation results illustrate that the performance of the proposed AVM approach can closely resemble the behavior of the SEM baseline with low harmonic distortion. To evaluate the performance of the proposed model, several case studies are investigated to verify the AFE rectifier operation, regarding mostly the total harmonic distortion (THD) wherein the THD percentages are improved to 4.78 and 2.5 from 5.14 and 2.78 for low- and high-power loads, respectively.

“…Moreover, a current modulation technique for the DR-EI is proposed in [31], [32], [33], [34], and [35] to mitigate specific harmonics. This current modulation technique is also utilised in a combination of DR-EI and parallel Silicon Controlled Rectifiers (SCR) with EI to improve the current harmonics [36], [37], [38].…”

This research work proposes a cost-effective Hybrid Active Harmonic Filter (HAHF) method to mitigate current harmonics in an industrial or commercial power network. The proposed HAHF is based on a Silicon-Controlled Rectifier with an Electronic Inductor (SCR-EI) topology with a reduced number of fully active switches and a better harmonic performance. A new shifted-pulse current modulation method is proposed to cancel harmonics caused by other converters. A Particle Swarm Optimisation (PSO) algorithm is implemented to optimise the modulation parameters and minimise the total harmonics. A lab prototype is implemented in the laboratory to validate the proposed mathematical method and simulation results.INDEX TERMS Active power filter, adjustable speed drives (ASD), harmonic mitigation, hybrid active harmonic filter, selective harmonic cancellation, power electronics, PSO algorithm.
