<span lang="EN-US">This paper proposes a new bidirectional step-up DC-DC converter, namely modified buck-boost converter. The proposed converter was derived from the conventional Output voltage expression of by considering drops across inductors and switching devices. results have shown that with same parameter input LC filter, has lower conduction losses. Moreover, rated filter capacitor...

This study examined the step-down DC-DC converter with high-efficiency appropriate for hybrid vehicles. The above described converter supplies power to electronic components such as headlights and air conditioners by replacing an electric generator of an internal combustion engine and converting the high voltage of a main battery to low voltage (12 V). In this study, the development specificati...

when intracranial pressure (icp) was uncontrollable among patients with severe traumatic brain injuries (stbi) and especially if it raises above 40 mmhg 100% morality was reported. eighty four percent of head injured patients would die if their initial icp is greater than 25 mm hg. decreasing icp through decompressive craniectomy (dc) theoretically may revert increased icp to normal and decreas...

In this paper, an integrated three-voltage-booster DC-DC (direct current to direct current) converter is proposed to achieve high voltage gain for renewable-energy generation systems. The proposed converter integrates three voltage-boosters into one power stage, which is composed of an active switch, a coupled-inductor, five diodes, and five capacitors. As compared with conventional high step-u...

objective: it is believed that monocyte isolation methods and maturation factors affect the phenotypic and functional characteristics of resultant dendritic cells (dc). in the present study, we compared two monocyte isolation methods, including plastic adherence-dendritic cells (adh-dc) and magnetic activated cell sorting- dendritic cells (macs-dc), and their effects on phagocytic activity of d...
