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. So it is the soft-switching (i.e. zero-voltage switching or zero-current switching) mechanism that can alleviate these shortcomings. In past, the researchers have proposed a numerous soft-switching topologies without giving attention to number of active and passive components. Hence it has been focused on optimization of number of active and passive components to be used in proposed topology. This article introduces a novel technique for soft-switching of a DC–DC buck converter, which is independent of snubber resistance and possesses only a snubber capacitor across each switch. The filter parameters of proposed structure are different than those of conventional one. With the inclusion of these filter parameters, the proposed structure is operated under zero-voltage switching or zero-current switching to enable the soft-switching of its devices. The designing technique of this proposed converter is properly narrated. The control strategy is quite simple. The MATLAB/Simulink (MATLAB 6.1 (Version)) model for the proposed topology is developed and its simulation is carried out to analyze its performance.
