Efficiency optimisation of ZVS isolated bidirectional DAB converters [PDF]
IET Power Electronics, 2018 This study presents a control method for isolated bidirectional dual‐active‐bridge converters to optimise the efficiency by achieving the zero‐voltage switching (ZVS) in high‐voltage applications, which the switching losses are the major issues. At light‐load condition, the duty control algorithm is proposed to achieve the ZVS for all switches while ...

Journal of Electrical and Computer Engineering, 2020 We study and describe mostly used traditional simplified circuits for full-bridge Zero Voltage Switching-Dual Active Bridge (ZVS-DAB) converter and deduce their mathematical model. On this basis, we propose a high-frequency (HF) mathematical model, which

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Molecular Oncology, EarlyView.Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Control Strategies for the DAB Based PV Interface System. [PDF]
PLoS ONE, 2016 This paper presents an interface system based on the Dual Active Bridge (DAB) converter for Photovoltaic (PV) arrays. Two control strategies are proposed for the DAB converter to harvest the maximum power from the PV array. The first strategy is based on

Peak Current Control and Feed-Forward Compensation for the DAB Converter
2019 IEEE International Conference on Industrial Technology (ICIT), 2019 This paper presents a double band peak current control for the DAB converter that permits to avoid the risk of transformer saturation. Additionally, feed-forward compensation is employed to achieve a fast transient response under load variations. The proposal is described, analyzed, and numerically simulated.
