This paper reviews state-of-the-art architectures for galvanically isolated DC–DC converters with data transmission low-power applications. Such applications do not have stringent requirements, in terms of power efficiency, but ask very compact, highly integrated implementations. To this aim, architecture simplicity is crucial, especially when and/or output regulation are required. Since the bo...

Due to the extensive role of non-isolated high step-up DC-DC converters (NHSDC)s in industrial applications and academic research, many these pulse width modulation have been presented recent years. For each NHSDCs, some claims are introduced verify its capabilities features, which has investigated review papers with different frameworks. Dissimilar previous papers, focused on classification de...

In this paper, a new configuration for symmetrical and asymmetrical multilevel inverters is proposed. In asymmetric mode, different algorithms are suggested in order to determine the magnitudes of DC voltage sources. The merit of this topology to the conventional symmetric and asymmetric inverters is verified by the provided comparisons. This topology uses a lower number of power electronic dev...

The need to integrate energy storage devices with renewable sources and improve the employed converters’ modulation control techniques continues grow. This trend is further activated by utilizing new converter topologies, such as high-frequency (HF) link converters. A dc-ac HF isolated presented in this paper a battery device three-phase grid. proposed composed of two stages. first stage direct...

The soft-switching technology is widely used in DC-DC converters, DC-AC inverters, and AC-DC rectifiers. Soft-switching non-isolated DC/DC converters (Buck, Boost, Buck-Boost) are the most active research area of technology, fruitful results achieved. However, there currently no comprehensive review for converters. This paper introduces topologies presents classification characteristic all kind...

variety of positive as well as negative regulatory signals are provided by antigen presenting cell in particular by dendritic cells. in this research, we studied the capacity of dendritic cells to expand antigen-specific t regulatory cells.we also investigated the role of tgf-beta in induction inhibitory functions of dendritic cells in mixed leukocyte reactions. dendritic cells were generated f...
