“…On the other hand, the front-end passive AC-DC converter, DBR, operates as a unidirectional uncontrolled rectifier to convert the AC mains signal to an unregulated DC voltage or a bridgeless AC-DC rectification in combination with a DC-DC converter can achieve a regulated output voltage with significant losses mitigation. Brief advantages and disadvantages of the half-bridge, full-bridge, and bridgeless type PFC converters are presented in TABLE IV [36], [38], [46] - [48].…”

“…The Boost-based topologies can be sorted approximately in terms of their power processing (incrementally), EMI noise (reduction), input ripple (reduction), and cost (incrementally) as follows: (1) bridgeless Boost topology, (2) bridgeless dual Boost topology, (3) totem-pole Boost topology, (4) interleaved Boost topology, (5) semibridgeless Boost topology, (6) phase-shifted semi-bridgeless Boost topology, (7) bridgeless interleaved Boost topology, (8) bridgeless interleaved resonant Boost topology, and ( 9) improved interleaved phase-shifted semi-bridgeless Boost topology. The aforementioned topologies are showcased in FIGURE 11 and FIGURE 12, and they are discussed in TABLE VI (merits versus demerits) and TABLE VII (power rating, pf, and THD) [10], [19], [35]- [38], [40], [60], [74]- [92]. In addition, in [93], a zero-voltage transition switch for the bridgeless Boost topology was addressed with several types of auxiliary circuits of zero current switching switches operation.…”

“…Also, this topology suffers from high EMI filter requirements due to the discontinuous input current. Another bridgeless Buck-Boost topology in DICM (FIGURE 17(b)) has been proposed in [38] for a 1 kW power charging EV application. This topology demonstrated high-power quality performance at 110 V input AC voltage and 400 V output DC voltage, where the input current THD was between 3.1%-4.1%, and unity pf was observed for power application in the range of 250 W-1 kW.…”

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.

“…With respect to the grid-side converter topology, the authors in [10][11][12][13] presented various bridge-less PFC topologies which reduce the overall conduction loss by reducing the number of rectifiers essentially eliminating the diode bridge rectifier that conducts the current from the input to the output. Similarly, in [14][15][16][17][18], the authors presented various topologies of PFC to obtain high efficiency as well as PF. Amongst various topologies, a bridge-less topology, i.e., totem pole, attracted enormous attention from researchers due to low conduction losses, less switching devices, and low common mode electromagnetic interferences (EMI).…”

In the present scenario of the fossil fuel crisis, a shift from conventional transportation to electric vehicles (EVs) is the goal, and it is necessary to make it economically feasible. Developing an efficient charger with mid-range power level may successfully resolve this problem. In this direction, an EV charging infrastructure has been proposed to achieve grid-to-vehicle (G2V) charging, with vehicle-to-grid (V2G) capability. In G2V mode, the proposed infrastructure consists of an on-board, single-phase, 7.7 kW totem pole converter in continuous conduction mode to achieve high-power factor correction (PFC). Additionally, instead of conventional Si power MOSFET, an SiC-based converter is introduced to lower the switching losses at high switching frequency with smaller filters. Using an SiC-based converter leads to increased efficiency (more than 98%) and reduced total harmonic distortion (less than 5%), making the system economical. Simultaneously, to make the system more economical, the proposed converter works as an inverter to feedback the power to the grid in V2G mode. Furthermore, to analyse the feasibility, the proposed infrastructure has been simulated and its performance is validated using the simpower tool in MATLAB/Simulink environment.

SummaryAs power factor correction rectifiers play a key component of electric vehicle (EV) battery charger, the advancements in designing of improved power quality‐based EV charger become more significant in modern era. This article exposes a single‐stage bridgeless isolated positive output (BIPO) Cuk PFC converter with a noninverted output signal. The input diode rectifier present at the input is redeemed by the bridgeless topology that eliminates the serious power quality (PQ) issues and proffers the eminent charging solution for the light electric vehicles (LEV). Unlike the conventional Cuk converter, the noninverted outcome of the BIPO converter does not require a separate amplifier for converting negative to positive output voltage. The preferred charger utilizes a single voltage and current sensor to synchronize the battery charging control in the constant current (CC) and constant voltage (CV) phases of charging. Therefore, the converter encompasses intrinsic zero current switching (ZCS) and offers low‐cost solution to the charger with reduced control complexities. The extensive state space approach is executed to analyze the marginal stability of the presented system. Moreover, the detailed loss modeling is addressed to show the charger's efficacy curve at the standard conditions. A hardware prototype of 350 W, 60 V/4 A charger is implemented to validate its steady‐state and dynamic performance.
