“…An improved bridgeless Ćuk topology has been introduced in [121] with a topology similar to FIGURE 23(c) to avoid the problems encountered by type 1 (FIGURE 23(a)) and type 2 (FIGURE 23(b)). Also, it eliminates the diode losses associated with the inactive switches in type 3 (FIGURE 23(c)) by applying a control signal to the inactive switch to disable the diodes' operation as a return path.…”

“…A single gate driver signal is provided to both switches in synchronism at each half-cycle. Therefore, the bridgeless Ćuk topology in [121] avoids the circulating current in the interleaved inductors, eliminates floating neutral points, and improves the converter efficiency by reducing the diode losses. An experimental prototype of the improved bridgeless Ćuk topology was developed in [121] for battery charging application up to 900W in DICM with input AC voltage between 110 V-220 V and output DC voltage by 300 V. The presented results showed an operating efficiency between 88%-92%, current THD less than 5%, and unity power factor for power between 150W and 850 W. In addition, the bridgeless Ćuk topology type 3 (FIGURE 23(c)) in [119] was compared to the topology in [121] for the same power range application.…”

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.

Resumo-Este artigo apresenta a análise estática, dinâmica e a validação experimental de um retificadoŕ Cuk monofásico dobrador de tensão operando no modo de condução descontínuo (MCD). A topologia proposta integra dois retificadoresĆuk clássicos através de um interruptor de três posições, o que dobra a tensão de saída ou reduz os esforços de tensão em relação à topologia clássica. A estrutura aumenta o ganho de tensão, mantendo a característica abaixadora/elevadora da famíliaĆuk. Além disto, parte dos componentes de potência são acionados somente em meio ciclo da rede elétrica, o que também reduz esforços de corrente nos semicondutores. Essas características permitem aumentar os níveis de potência e de tensão de operação do conversoŕ Cuk. A topologia proposta foi analisada no MCD, modo no qual o alto fator de potência é naturalmente obtido sem a necessidade de uma malha de controle de corrente. De modo a corroborar a análise teórica desenvolvida, foi construído um protótipo em laboratório de 1 kW, com tensão eficaz de entrada de 220 V, tensão de saída de 400 V e frequência de comutação de 50 kHz. São apresentados resultados experimentais com malha de controle da tensão de saída, sendo que, em potência nominal, o retificadoŕ Cuk dobrador de tensão atingiu um rendimento de 94,68% e uma corrente de entrada com THD de 1,86%.

SummaryPower solutions contribute a remarkable role in all the sectors. In order to develop the sustainable and affodable power solution, the bettered power quality (PQ) based modified bridgeless switched inductor (MBSL) Sepic power factor correction (PFC) converter is introduced in this article. An added feature to an already existing traditional Sepic converter resulted in switched inductor (SL) network that reasonably improves the step‐down voltage gain with low current stress across the output inductors and diodes which restricts the utilization of transformer that ultimately reduces the overall cost of power solution. This introduced structure acts as a good choice of low‐cost power conversion solution in the perspective of improved inline PQ indices, high efficiency and good reliability. Furthermore, the discontinuous conduction mode (DCM) functioning of SL network reveals the innate zero current switching (ZCS) capability with enhanced efficiency. Besides, the effective functionality of the one‐stage PFC converter is tested on hardware prototype of 250 W/48 V, and it also adopts an appropriate control approach to stabilize the output voltage. This study also exposes small signal modeling to prove the stability of the power solution. In addition, the test outcomes reveal that the preferred PFC procure sinusoidal current from the AC mains that confirms the good enshaping attribute and low current harmonic distortions within the stipulated IEC 61000‐3‐2 standard guidelines for both standstill and fluctuating conditions.
