“…This configuration includes two additional diodes (D 3 and D 4 ) to the symmetrical topology. As a result, this topology is built by two boost converters, each one operating in each semi-cycle of the AC sinusoidal wave [13,38,72,89,[96][97][98][99][100]. For this reason, this topology is also known as dual boost PFC rectifier.…”

Power Factor Correction (PFC) single-phase AC/DC converters are used in several power electronics applications as full wave control rectifiers improving power quality and providing high standards of efficiency. Many papers dealing with the description or use of such topologies have been published in recent years; however, a review that describes and organizes their specific details has not been reported in the technical literature. Therefore, this paper presents an extensive review of PFC single-phase AC/DC converters operating with the Boost converter topology for low and medium voltage as well as and power appliances. A categorization of bridge, semi-bridgeless, and bridgeless, in accordance with the construction characteristics, was carried out in order to unify the technical terminology. Benefits and disadvantages are described and analyzed in detail. Furthermore, a comparison performance in terms of PFC, Total Harmonic Distortion (THD), power capacity, electromagnetic compatibility (EMC), number of elements, and efficiency is included.

This study presents a zero-voltage-transition (ZVT) bridgeless power factor correction (PFC) rectifier, which uses an auxiliary circuit with a transformer to achieve soft-switching for the main power switches. With the auxiliary circuit, the main switches can be ZVT turned-on without any additional voltage or current stresses. In addition, the auxiliary switch is turned-off with zero-current switching. Therefore, the switching loss of all power switches is reduced, and the overall rectifier efficiency is improved. The circuit topology, operation analysis and the components selection of the proposed rectifier are described in detail. Finally, a laboratory prototype of 700 W is implemented and tested to verify the performance of the proposed PFC rectifier.

“…This may increase switching losses and components. However, as these power converters have to meet very high load demand, which leads to more heat dissipation and high rating of the device, modular converters with different configurations are arrived employing various control methods [14][15][16][17]. Among the various three-phase circuit topologies for power-factor correction (PFC) [18], these modular AC to DC converters have many advantages like flexible load demand, effective current sharing and reduced voltage stress on the switches.…”

Power electronic converters play a major role in wind energy conversion systems (WECS). A typical variable speed WECS includes wind turbine, permanent magnet synchronous generator (PMSG) and power conditioners. In this study, a three-phase modular boost converter supplied from a PMSG and controlled using a linear quadratic regulator (LQR) is proposed for battery charging applications. Each phase of PMSG is connected to a single phase diode rectifier and a DC-DC boost converter. All boost converters have a common output capacitor and load. The proportionalintegral-based voltage controller provides voltage regulation on the DC side. A fixed frequency LQR-based current controller applied for the individual phases provides a better three-phase source utilisation. The instantaneous pq theory is adopted for the reference current calculation. Extensive simulation studies based on the models developed using MATLAB/SIMULINK reveal that the proposed system performs satisfactorily for step variations in wind speed and load. The performance of the low power prototype developed and controlled using a dSPACE 1104 digital signal processor shows good output voltage regulation and better source utilisation for wide variations in load.
