Analysis of a Novel Soft-Switching DC–DC Converter for Reduction in Switching Loss

Power Electronics and Drives
The conventional buck converter is the first and foremost member among the family of DC–DC converters. Major drawback of the conventional buck converter is the hard-switching that leads to many shortcomings and finally leads to poor efficiency.
