Buck-Converter Design Demystified Stepdown (buck) switching converters are integral to modern electronics. They can convert a voltage source (typically 8 V to 25 V) into a lower regulated voltage (typically 0.5 V to 5 V). Stepdown converters transfer small packets of energy using a switch‚ a diode‚ an inductor and several capacitors. Though substantially larger and noisier than their linear-regulator counterparts‚ buck converters offer higher efficiency in most cases. Despite their widespread use

Power Supply Regulation DC-DC voltage converters are often used to provide a regulated voltage supply from an unregulated voltage source. Unregulated voltage sources can be rectified line voltages that exhibit fluctuations due to changes in magnitude. Regulated voltage supplies provide an average DC output voltage at a desired level (3.3 V‚ 2.5 V‚ etc.)‚ despite fluctuating input voltage sources and variable output loads. Factors to consider when deciding on a regulated voltage supply solution include:

Abstract— In the conventional buck converter the supply current is discontinuous which may produce electromagnetic interference (EMI). In order to minimize the EMI problems an interleaved buck converter with continuous supply current has been introduced. Also due to the advantage of improved step-down conversion ratio‚ the interleaved buck converter can be used for high step-down and high frequency applications. The main features of the converter also include lower switch stress and lower output

Ways To Reduce The Effects of Pollution Nowadays‚ pollution has become a major issue that concerns all countries worldwide. Majority of the pollution are results of the selfish behaviour of humans. There are many types of pollutions‚ examples are water pollution and air pollution. Each of this pollution can be dealt with different methods depending on the source of the error. In general‚ both air and water pollution can be reduced by utilizing the modern technology that humans have developed
