“…Nonetheless, this operation mode produces a random ripple to consider in control designing. In addition, power losses can be mitigated with snubber circuits [92,[116][117][118][119][120][121][122]. This topology has commonly been used in low voltage and power applications; nevertheless, in medium power applications, it is suggested to build the converter with switches (Q 1 and Q 2 ) using GaN technology [123].…”

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.

“…Moreover, the buck-boost operation in DCM possesses high THD due to the discontinuous input current [3], while the SEPIC typology produces high ripple at the output. Other research efforts have introduced quasi-resonant [8] and three-port quasi single-stage [9] bridgeless PFC converters, but both converters require multiple switches for operation. Totempole bridgeless PFC converters have also been presented to mitigate the inrush current [10] and zero-crossing distortion [11] issues.…”

In this paper, an averaged nonlinear model of a bridgeless single-switch non-inverting ac-dc Cuk converter in DCM is derived. In addition, a current-mode control scheme is designed to operate the power converter in buck and boost modes during line and load variations. In contrast, the previous research endeavors of the bridgeless Cuk converter presented a single operation mode, and accommodation of large disturbances has not been discussed. The proposed control method is compared with the classical PI controller to investigate their performance. MATLAB simulation results show that the proposed control scheme improves the dynamical response, tracks the reference voltage, and provides wide operating range.

“…The applications of AC–DC converters include battery charger [1–6], light‐emitting diode (LED) lighting [7–16], electric vehicle (EV) [17, 18] and laptop computer [19, 20]. A two‐stage PFC power converter [1, 2, 21–24] is a series connection of an AC–DC converter for correcting PF and a DC–DC one for regulating the output voltage. The two‐stage AC–DC converter requires at least two power switches and two individual controllers, which leads to a high cost and a large volume.…”

“…This is because most of them are hard‐switching converters [9–14], which generate large switching losses. For power‐conversion efficiency improvements, the resonant topologies, such as the LLC converters [4, 5, 15, 30, 31] and class‐E converters [7, 8, 16, 21, 32–39], have also been applied to the AC–DC converters [4–8, 15, 16, 20–23, 30–32]. The resonant converters have more circuit components than the traditional converters because of the resonant circuit.…”

This paper presents a single-switch zero-voltage switching (ZVS) power-factor correction converter based on the class-E 2 converter at 1 MHz switching frequency. A design method for ensuring the ZVS for the entire line-voltage period is proposed. By visualising the ZVS region in the parameter space, circuit parameters can be easily obtained to achieve the ZVS for the entire line-voltage period. Additionally, a closed-loop controller is applied for achieving a high power factor, low total harmonic distortion of the input current and output voltage regulation. The experimental circuit achieved the ZVS in the entire line-voltage period against load variations. As a result, the implemented converter achieved the same level of power-conversion efficiency as the 100-kHz power-factor correction converters and a high power factor with low total harmonic distortion, which denoted the effectiveness of the proposed design method. INTRODUCTIONAC-DC power supplies with power factor correction (PFC) are used in a wide range of applications. The applications of AC-DC converters include battery charger [1-6], light-emitting diode (LED) lighting [7-16], electric vehicle (EV) [17, 18] and laptop computer [19, 20]. A two-stage PFC power converter [1, 2, 21-24] is a series connection of an AC-DC converter for correcting PF and a DC-DC one for regulating the output voltage. The two-stage AC-DC converter requires at least two power switches and two individual controllers, which leads to a high cost and a large volume. On the other hand, a single-stage AC-DC converter combines the PFC stage and the voltageregulating one into a single converter [3-16, 20, 24-31]. Therefore, single-stage converters have a small component number and achieve low costs compared with two-stage converters, and are often applied for space-constrained applications such as battery chargers [3-6]. Traditional converter topologies, such as boost [11, 12], buck [13], buck-boost [13, 14], and Flyback converters [9, 10],This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
