“…For a three-phase source, many topologies are presented in the literature. 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].…”

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.

“…A technique for enhancing the capacity of synchronous generators at the distant ends of rural distribution where the power factor was small and the line resistance was high. These methods have been proposed only for the inductive loads [19], [20]. If the power factor is lagging, the system starts consuming more power from utility and the extra power utility gives a penalty [21].…”

For all industrial and distribution sites, the lagging power factor of electrical loads is a common problem. In the early days, it was corrected manually by adding the capacitor banks of certain values in parallel. Automatic power factor correction (APFC) using a capacitor bank helps to make a power factor that is close to unity. It consists of a microcontroller that processes the value of the power factor to enable the system and monitor the power factor if it falls below (0.77) from the specified level. This paper presents the automatic correction of the power factor by adding the capacitors banks automatically of the desired value in a three-phase system in the form of binary coding (0-7). The main purpose of this system is to maintain the power factor as close as to unity, for the experimental case, it is set to (0.93) which helps to decreases the losses and ultimately increase the efficiency of the system.

“…Fewer semiconductors than any other topology of its kind have been used in the proposed converter. Azazi, H.Z presents a single-stage, three-phase power factor correction (PFC) rectifier using a single-switch boost regulator with less than 5% total harmonic distortion (THD) in the supply current [6]. A three-phase, single-stage AC-DC converter with topology utilizing SiC MOSFETs is proposed and analyzed by Zhang, Z [7].…”

An active clamp, three-phase, six-switch power factor correction rectifier with a one-cycle controller is proposed, which can effectively suppress the reverse recovery of the reverse parallel diode of the bridge arm switch and reduce the reverse recovery loss. The main switches and auxiliary switch are both zero-voltage switches. It works in a fixed switching frequency and low power stress during the switching period. The specific working process and control circuit are analyzed in detail, and the model simulation is carried out. The experimental platform of a 2.5 KW prototype, with a complete test and verification of the soft switch technology proposed in this paper, was set up in the laboratory.
