"An Improved Buck Converter with Zero Output Current Ripple and Soft-Sw" by Shamim Mohammadsalehian, Parham Mohseni et al.
This study presents a simple auxiliary circuit to provide a soft-switching condition in the conventional buck converter without an additional active component. Advantages of the proposed structure can be summarized as decreased switching losses by structure operation under zero voltage switching (ZVS) conditions, declined reverse recovery losses of diodes by providing zero current switching (ZCS) turn off condition, and reduced the output current ripple to near zero. The proposed auxiliary circuit and its performance with the conventional buck converter have been analyzed in details. Also, the...
