Power electronic converters play a vital role in a power system and the most commonly used type of DC/DC converters is buck converter. This is due to the fact that buck converters are widely used to step down the voltage as well as they provide good voltage regulation in critical applications including power supplies for data centers. Therefore, designing a(More)
Demand of power is increasing worldwide and this increased demand has motivated the engineers to look for alternative or renewable energy systems. Meanwhile, the data centers are also employing the solar energy systems to avoid the AC/DC power conversion losses due to the fact that an efficient solar system with DC/DC converter will help them to save up to(More)
