“…The results indicate that genetic-algorithm-based average current control performs better in terms of power factor, THD, and UPF without a filter requirement at the source side under disturbances in the source and load sides. A threephase Vienna AC/DC converter with power factor correction in which (field-programmable gate array) FPGA-based emulation was implemented for generating switching pattern was proposed in a previous study [13]. In the proposed scheme, the control scheme was implemented by incorporating Hardware-inthe-Loop testing in the system, thereby increasing the accuracy.…”

Bridgeless single-stage converters are used for efficient (alternative current) AC-(direct current) DC conversion. These converters control generators, like electromagnetic meso-and micro-scale generators with low voltage. Power factor correction helps increase the factor of the power supply. The main advantage of the power factor is it shapes the input current for increasing the real power of the AC supply. In this paper, a two-switch bridgeless rectifier topology is designed with a power factor correction capability. For the proposed converter topology to have good power quality parameters, the closed loop scheme, which uses the grey wolf optimization (GWO) algorithm, is implemented. The successes of GWO encourage this research to implement GWO in the topology. The performance of the proposed topology is analyzed under different load conditions. Simulation is carried out using the MATLAB/Simulink environment, and the results are compared with those of conventional (proportional integral derivative) PID and (particle swarm optimization) PSO controllers. To validate the simulation results, a 350-W hardware prototype is implemented, and the voltage ripple, efficiency, and power factor under different load conditions are analyzed and tabulated. The comparative study clearly indicates that the proposed converter topology with a closed loop control scheme using the GWO algorithm improves the power factor to 0.9732 and reduces the voltage ripple to 0.12% with a conversion efficiency of 98.25%.

“…Six controlled switch converters are effective for high power levels, but when it comes to systems with lower power levels, where only unidirectional power flow is required, rectifiers with a reduced number of active elements (single or three controlled switches) operating in the DCM are usually preferred, and the three-phase boost is the most used [7][8][9][10][11][12]. A variety of solutions has recently arisen [13][14][15][16][17][18][19][20][21][22]. In the analysis of the power conversion from the grid to DC bus, the input RMS voltage is almost constant, maintained in the range given by standards.…”

A discontinuous conduction mode (DCM) three-phase single-ended primary-inductor converter (SEPIC) is presented in this article. The analyzed converter operates as a high-power factor stage in AC–DC conversion systems. As its main features, it presents three controlled switches and a single control signal with simple implementation and low-current harmonic distortion. The converter topology, its design equations, and its operation modes are presented as well as a simulation analysis considering a 3 kW–220 V three-phase input to 400 V DC output converter. The experimental results are included, considering as an application the rectifier stage in low-power wind energy conversion systems (WECS) based on a 1 kW permanent magnet synchronous generator (PMSG) with variable voltage frequencies. From the analysis performed in the paper and the simulation and experimental results revealed, it is concluded that the converter is indicated to be employed in any AC–DC low-power conversion system, such as DC distribution systems, and distributed generation or hybrid systems containing variable-frequency generation.
