A Family of Single-Phase Hybrid Step-Down PFC Converters

Critical conduction mode Buck-Buck/Boost converter with high efficiency

“…Xie, Zhao, Lu, and Liu (2013) have put forward a new topology which combines buck and flyback converter to eliminate the dead zone. Zhang, Zhao, Zhao, and Wu (2017) have proposed a topology which combines buck converter with flyback converter. Yao et al (2017) have proposed an injecting third harmonic method to realize high PF.…”

Efficient bridgeless SEPIC converter fed PMBLDC motor using artificial neural network

“…Bridgeless PFC topologies are proposed topology can reduce conduction losses from rectifying bridges; thus, overall system efficiency can be increased. Unlike the boost, the SEPIC and bridgeless SEPIC converters have many several benefits in PFC applications, such as easier implementation of transformer isolation, input surge current limitation during startup and full-load conditions, lower input current ripple, and less electromagnetic interference [11][12][13][14][15].…”

A Sliding Surface-Regulated Current-Mode Pulse-Width Modulation Controller for a Digital Signal Processor-Based Single Ended Primary Inductor Converter-Type Power Factor Correction Rectifier

“…During the past twenty years, numerous publications on the development of power-factorcorrection (PFC) pulse-width modulation (PWM) AC-to-DC converters have been published [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In these switched-mode PFC converters, an idea about how to achieve zero reactive power with unity power factor (UPF) in AC source line is often discussed.…”

“…Two classes roughly grouped from the presented PFC schemes are as follows: (1) integration and modification in hardware circuits of power converters [1][2][3][4][5][6][7][8][9]; and (2) application of the developed control techniques to AC-to-DC or DC-to-DC converters [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The studies in [1][2][3][4][5][6][7][8][9] can be summarized as follows: in [1,2], an additional LC-diode clamper or snubber was integrated into the specified or multilevel converters so that the PFC was completed through the additional clamper or snubber. In [3][4][5][6], an integration of the selected two types of converters or an auxiliary circuit were employed to form a PFC rectifier or converter.…”

Furthermore, a multiple-level conversion stage [7], a modified converter topology [8], and a three-phase SEPIC converter under discontinuous conduction mode operation [9] were proposed.…”
