“…where f is the switching frequency, D is the duty cycle of the converter and is the current ripple of each phase. Considering the advantage of current cancelation in the IBC ,which results in a low output current, a current ripple of = 25 was selected for each phase to minimise the size of the inductor [36]- [38]. This leads to an inductance value of = 233.…”

This paper introduces a level 3 charging system which aims to reduce the charging time to less than 15 minutes with 350 kW charging power. Two architectures of a fast charging station based on the isolation requirement through low and high-frequency transformers are introduced and discussed. Focusing on the DC-DC charging stage, this paper also provides a detailed comparison of the Dual Active Bridge (DAB) converter and the Interleaved Buck Converter (IBC), which are considered as two of the most suitable converters that can serve as a fast DC charger. Technical evaluation and comparison based on different performance indices such as volume, efficiency, number of components etc. as well as simulation of the two converters are presented. Finally, comparison results are introduced and a final discussion and conclusion are presented on which topology seems more optimum to be used as a fast DC charger.

“…For this study, it is not possible to capture all the UFCS topologies mentioned in the literature. To illustrate the impact of a typical future UFCS impact on the power grid resonance behaviour, a simple two-level AFE with stationary battery storage topology has been chosen for this study due to its prevailing presence in the literature [8,9] and technology readiness for mass production.

“…A conversão CC-CC pode ser realizada por conversores interleaved, os quais apresentam vantagens quando utilizados para potências elevadas, entre elas reduzidas ondulações da corrente de entrada e da tensão de saída, reduzido tamanho dos componentes passivos e alta eficiência em comparação com outras topologias [13], [16], [18], [21]. Em [23] a topologia boost-interleaved é implementada em 750 kW.…”

O aprimoramento da infraestrutura de carregamento dos veículos elétricos é fundamental para a sua ampla adoção. Dessa forma, este artigo propõe uma estação modular de carregamento rápido com filtro ativo de potência e elemento armazenador de energia para veículos elétricos. A estação é conectada em média tensão e composta por 10 pontos de carregamento de 60 kW cada um, em acordo com as normas vigentes para carregamento rápido. Normas as quais são inicialmente revisadas e descritas. O filtro ativo de potência é apresentado, analisado e projetado para reduzir harmônicas de corrente no ponto de conexão com a rede de distribuição primária. Além disso, é realizada a análise de estabilidade na conexão dos conversores. Os resultados experimentais no Typhoon HIL comprovam o funcionamento da estação em acordo com as exigências normativas internacionais.
