“…The input current distortion (THD) analyzed governed by IEC 6100-4-7 which requires data acquisition in blocks of 200 𝑚𝑠 with no gapped or overlap between the acquired data block [37]. Thus, total 10 cycles of input current were considered in measurement of input current harmonic.…”

This paper proposes an isolated full bridgeless single stage alternating current-direct current (AC-DC) converter. The proposed converter integrates the operation of a pure bridgeless power factor correction with input boost inductor cascaded with center-tap transformer and half bridge circuit. In addition, the bidirectional switch can be driven with single control signal which further simplifies the controller circuit. It is also proved that this converter reduces the total number of components compared to some conventional circuit and semi-bridgeless circuit topologies. The circuit operation of the proposed circuit is then confirmed with the small signal model, large signal model, circuit simulation and then verified experimentally. It is designed and tested at 115 Vac, 50 Hz of input supply, and 20 Vdc output voltage with maximum output power of 100 W. In addition, the crossover distortion at the input current is minimize at high input line frequency.

“…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.

“…The bridgeless PFC rectifier attracts more attention for its ability to decrease transmission losses. Figure 2 shows the schema of a BBPFC rectifier circuit (Su et al 2011, Muhammad and Lu 2012, Santos and Barrero 2013, Lu et al 2015, Musavi et al 2011, Cho 2014. As exhibited in Figure 3, there is one active switch at each half cycle.…”

The existence of harmonics in the DG systems ends up with some impacts, including increased heat losses in transformers, electrical motors, and power lines; low power factor; insufficient usage of distribution cable and plant. Conventional passive filters PF have been used in order to meet the standards such as IEEE-519 and IEC-555, to compensate DG systems harmonics, and to develop power quality, but are often not ideal due to increased cost, fixed compensation, large size, and resonance problems (Akagi et al. 2007). Recently, power factor correction (PFC) rectifiers are included as aninherent part of the AC-DC transformation systems. PFC rectifierseliminate harmonics at the input
