“…Leakage inductance, therefore, determines the maximum transferable power for a given switching frequency. Zero-voltage switching can be achieved using the internal leakage inductance of the transformer [17] - [18]. Our goals in this paper are a comparison between the planar transformer and wire-wound transformer in winding loss and core loss.…”

“…O conversor é proposto para aplicações industriais, utiliza a técnica de phase-shift e um transformador conectado em Y-Y , possibilitando fluxo bidirecional de energia em alta potência [5]. O desenvolvimento de estruturas ressonantes deste conversor também impulsionou diversas pesquisas acadêmicas e industriais [6]- [10], com o principal objetivo de obter melhor eficiência e comutação suave do tipo Zero-Voltage-Switching / Zero-Current-Switching (ZVS / ZCS). No entanto, um inconveniente destes tipos de conversores ressonantes são os elevados esforços de corrente nos interruptores, que podem limitar o nível de potência processada e reduzir o rendimento da estrutura [11].…”

Este artigo apresenta uma nova topologia de conversor CC-CC bidirecional Push-Pull / Flyback que, em ambos os sentidos de operação, são estudados detalhadamente, incluindo a análise teórica e matemática, o ganho estático nos três modos de condução que são modo contínuo, descontínuo e crítico, além de resultados experimentais. O conversor proposto é adequado para o barramento de corrente contínua (CC) em micro-redes onde são aplicados acumuladores de energia e fontes em CC do tipo células de combustível, gerador fotovoltaico e turbina eólica. Permite fluxo bidirecional de energia, elevado ganho de tensão e possibilita a integração desses sistemas a baterias e ultracapacitores que apresentam características de baixa tensão de saída e exigem correntes elevadas com baixa ondulação. A viabilidade deste conversor com isolação galvânica é demonstrada pelos resultados obtidos por meio de um protótipo com potência nominal no sentido direto de 4 kW e rendimento acima de 90,1 % , e potência de 1,3 kW com rendimento de 84,3 % no sentido inverso do fluxo de potência.

The three-phase dual active bridge (3p-DAB) topology has been widely applied in high power dc-dc conversion, which has advantages of bidirectional power transfer, inherent soft switching capability and small filter size. The phase shift control is the conventional modulation strategy for three-phase DAB. However, the conventional control strategy can't operate the converter under soft switching at low loads, especially when the voltage conversion ratio is far from the unit ratio. The aim of this paper is to propose a novel simultaneous pulse-widthmodulation (PWM) control strategy for the three-phase DAB to realize zero-voltage-switching (ZVS) in the whole load range. Seven switching modes are confirmed based on relative relationships of control parameters. The transmission power is calculated and soft switching operation is analyzed in each switching mode. Comparative analysis of ZVS operation with the conventional phase shift control and the proposed control strategy is then presented. A three-phase DAB converter is modeled in Saber and improvements by applying the proposed control strategy are verified by the simulation results.
