Transformer-Coupled Converter for Voltage Modulation Techniques [PDF]
IEEE Transactions on Power Electronics, 2013 In high performance digital systems as well as in RF systems, voltage scaling and modulation techniques have been adopted to achieve a more efficient processing of the energy. The implementation of such techniques relies on a power supply that is capable of rapidly adjusting the system supply voltage.

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 ...

Core-less multiphase converter with transformer coupling [PDF]
2010 IEEE Energy Conversion Congress and Exposition, 2010 A coupled multiphase converter where the coupling among the phases is done using core-less planar transformers is presented in this paper. Operating principle of the transformer-coupled converter has been presented previously in the literature and in this paper this concept is applied to develop a core-less converter.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Noise characteristics and prediction methods of operating converter transformers
电力工程技术Due to the presence of harmonics, the noise characteristics of converter transformers differ significantly from those of ordinary transformers. Currently, the mechanism through which harmonics affect noise is not clearly understood, necessitating ...
