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.

“…The transfer function of the system can be found using the equation as given in [31]

G ()(, s) = V_{0} ()(, s) / V ()(, s) = C false(s I - A false)^{- 1} B .

By substituting the designed values of passive components provided in the (12)–(19), the transfer function of the system is obtained as

G false(s false) = \frac{5.7 \times 10^{- 15} s^{3} + 4.3 \times 10^{- 7} s + 0.695 \times 10^{14}}{s^{4} + 2.4 s^{3} + 0.75 \times 10^{9} s^{2} + 11.5 \times 10^{11} s + 0.85 \times 10^{15}} .

Closed loop transfer function of PI controller is

G false(s false) = K_{normalp} + \frac{K_{normali}}{s} .

Using the transfer function (28), Ziegler Nichols method [23, 32] tuned values of K p and K i are obtained as 0.001 and 0.375, respectively. Bode plot of the whole system has been plotted using converter and compensator transfer function [25].…”

“…Also, no separate control block has to be provided for safeguarding power switches from attack of inrush/over load current [16]. Bridgeless configurations of Cuk, Sepic and Zeta converters are widely preferred for power quality improvement at source side [17][18][19][20][21][22][23]. In the recent days, DC-DC Luo converter with the ability of its voltage lifting technique attracts many researchers.…”

Power factor corrected AC-DC converter topologies have been of research interest for DC power supplies. The main goal of this work is to improve power quality at the supply side and maintain constant DC voltage at the output side by designing a Modified Bridge Less Positive Output Luo (MBLPOL) power factor correction (PFC) converter. Discontinuous conduction mode is also possible for input PFC with a small filter at the source side. In order to regulate the DC load voltage for various loads and supply voltage conditions, a feedback control circuit with a single voltage sensor is proposed for the PFC converter. A prototype of 100 W, 48 V, AC-DC MBLPOL converter is designed and tested. Proper design of controller for the converter guarantees the excellent performance and the same is validated with the help of simulation and hardware results. The proposed MBLPOL converter is tested for DC load voltage regulation for various load power and supply voltage variations. The experimental study shows supply current total harmonic distortion of 1.24% at rated load while maintaining unity power factor.

This research paper proposes an enhanced power quality in bridgeless modified Landsman-Canonical switching cell (BMLCSC) converter used for arc welding power supplies. This proposed converter topology is presented for circuit component reduction to eliminate the need for a diode bridge rectifier and input filter to make the circuit more compact. The proposed converter is operated on discontinuous conduction mode (DCM). A closed loop PI control circuit with a single voltage sensor is utilized to achieve load regulation, line regulation with high efficiency and quick response. The exploratory performance of preferred framework is simulated using Matlab/Simulink and validated with a hardware prototype of 100 W, 48 V.
