    Abstract: This paper presents the design and modeling of synchronous DC-DC buck converter for device applications low consumption using Matlab/Simulink. In this work, the steady-state and average-value models for buck converter are analysed and it offers the modeled equations and simulation techniques of standard buck converter topology including variable lo...

    Abstract: The chemically modified silica gel with 3-aminopropyltrimethoxysilane groups and EDTA was used to immobilize ruthenium complex initially. These materials were incorporated into a carbon paste electrode and its electrochemical properties were investigated. However, for ascorbic acid solution, an enhancement of the anodic peak current was detected du... Show More
