“…Besides, it is efficient in open circuit operation. Also, it is resilient to inrush input current issues [35], [53], [58], [59]. The Buck topology is usually employed in low-power applications (< 300 W) where the converter can attain the input current' harmonic elements within the margins of the IEC 61000-3-2 requirements [50].…”

“…A similar topology has been tackled in [94] (a bridgeless Buck converter (FIGURE 14(b))); yet, the performance evaluation was limited to 120 W. In [58], a modified bridgeless Buck topology has been developed to address the dead-angle issue by integrating a fly-back circuit; nonetheless, the proposed design was limited to a low-power range (up to 100 W). Also, a bridgeless Buck topology with dual-switch (FIGURE 14(c)) and single-switch (FIGURE 14(d)) configurations in DCVM (i.e., bridgeless Buck with additional LC input circuit) has been addressed in [50] to achieve the advantages of both the CICM and DICM (i.e., simple control and reduced current stress) with high operating efficiency for applications up to 100 W.…”

Electrification of the transportation sector has originated a worldwide demand towards greenbased refueling infrastructure modernization. Global researches and efforts have been pondered to promote optimal Electric Vehicle (EV) charging stations. The EV power electronic systems can be classified into three main divisions: power charging station configuration (e.g., Level 1 (i.e., slow-speed charger), Level 2 (i.e., fast-speed charger), and Level 3 (i.e., ultra-fast speed charger)), the electric drive system, and the auxiliary EV loads. This paper emphasizes the recent development in Power Factor Correction (PFC) converters in the on-board charger system for short-distance EVs (e.g., e-bikes, e-trikes, e-rickshaw, and golf carts) and longdistance EVs (passenger e-cars, e-trucks, and e-buses). The EV battery voltage mainly ranges between 36 V and 900 V based on the EV application. The on-board battery charger consists of either a single-stage converter (a PFC converter that meets the demands of both the supply-side and the battery-side) or a twostage converter (a PFC converter that meets the supply-side requirements and a DC-DC converter that meets the battery-side requirements). This paper focuses on the single-phase unidirectional non-isolated PFC converters for on-board battery chargers (i.e., Level 1 and Level 2 charging infrastructure). A comprehensive classification is provided for the PFC converters with two main categories: (1) the fundamental PFC topologies (i.e., Buck, Boost, Buck-Boost, SEPIC, Ćuk, and Zeta converters) and (2) the modified PFC topologies (i.e., improved power quality PFC converters derived from the fundamental topologies). This paper provides a review of up-to-date publications for PFC converters in short-/long-distance EV applications.

“…Moreover, this modification can automatically eliminate the input current dead zones, since the integrated inductor turns this IPOP buck topology to flyback mode when the dead zones come. Apart from this solution, this input current dead zone issue can also be solved by using a relatively complicated control method, e.g., a modified IPOS buck topology with four active switches [36]. In contrast, another topological solution adopting only simple control is using a switch-integrated parallel buck and flyback converter cell to form the IPOP configuration, but it has poor efficiency for too many components employed [37].…”

This paper introduces two general ways to derive single-phase bridgeless power factor correction (PFC) topologies and then 15 accessible bridgeless topologies are derived based on the configuration of different basic types of DC-DC converter cells. Although the majority of the topologies have been previously proposed, other possible research points are reviewed. Besides, a consistent component sizing procedure with electric, thermal, and cost models is applied to conduct the performance benchmarking of these PFC topologies in terms of power loss, volume, and cost. Three boost-type PFC topologies are chosen as examples to demonstrate the procedure and the corresponding benchmarking results with both theoretical analyses and experimental verification. Finally, mission profiles of one specific application are introduced to show the material cost payback period of adopting one modified bridgeless boost topology instead of conventional one in different scenarios.

“…Thus, dead angle problem must be eliminated [13]. Several topologies are introduced in [14–20] to solve dead angle problem but all of them suffer from the hard switching condition. In [21–25] buck‐boost PFC is used, hence there is no dead angle problem.…”

Here, a new single stage single switch soft switching PFC (power factor correction) converter is presented and analysed. The proposed converter combines buck AC‐DC converter and forward DC‐DC converter and applies an auxiliary circuit to eliminate input current dead angle. Furthermore, soft switching is attained and switching losses are eliminated resulting in high efficiency. Another merit of the proposed converter is the partial direct transmission of input power to the output that helps to improve efficiency. Experimental results are presented which justify the above mentioned points and show less than 5% THD in the nominal load. Comparison with other similar single stage PFC converters is performed and shows the proposed converter provides the lowest THD while high efficiency is attained.
