This work presents, phase modulated current fed DC/DC converter has been developed for fuel/photovoltaic cell standalone system, and it interfaces the low voltage output fuel/photovoltaic cell powered higher voltage DC bus system (255 V–425 V). The purpose of transformer is to provide the protection by providing matching voltage level and galvanic isolation. Stepped up DC voltage is then inverted...
In this paper, implementation and comparisons of Nearest Vector Control and Nearest Level Control modulation techniques for 27-Level with 3-Cell Asymmetrical Cascaded H-Bridge Multilevel Inverter is presented to analyse the performance and application oriented complexity. Asymmetrical type of multilevel inverters is familiar in the view of attaining more number of levels with lesser number of cells...
Pressure switches are the most important entities used in the process industry. A pressure switch is an instrument designed to have a switching action on the process pressure. This paper gives a detailed study and analysis of the pressure switch. This article also throws some light on various kinds of routine and type tests performed on the pressure switch, to ensure the proper functioning of the...
