Analysis of synchronous and interleaved converter

Abstract

Converter circuits are different kinds of power electronics circuit which analysis the current and voltages from one level to another level with the importance of high efficiency. In the new era of power electronics, the voltages and current can be calculated and thus the power analysis is maintained for effective and stable electronics circuits. For the need of power electronics engineers, the output voltage must be low for the high source voltages for different devices where a buck converter is used. In telecommunication power supply system, buck converter is also used to take care the power quality issues. It is worked on modern electronic devices and telecommunication power supply system by using several mathematical methods of converters. Different power theories are considered to validate the work. Finally, switching frequency is fixed according to operating range. However it cannot make that converter effective and efficient, for that purpose the synchronous and interleaved buck converter is analyzed here. The one of the benefits of interleaving synchronous buck converter is reducing the ripple current which makes that convert more convenient. Moreover for developed electronics devices it may need higher voltages than the source voltages and in that case a boost converter is being used here. Furthermore, for more efficient circuit the interleaved boost converters are analyzed here. One of the major purposes of analyzing interleaved boost converters is the reduction of output voltage ripple over the conventional boost converters which makes the converter more effective. Therefore, it is essential to improve the converter circuits by using the method of interleaving for an efficient system. Later, by varying the duty cycles and the input voltages, the ripple voltages and currents are reduced which provide highest efficiency of that converter hence the efficiency is calculated and is taken the most effective factors of that converter.
