High-Efficiency Stacked Interleaved Buck Converter Employing Series Capacitor and Coupled Inductor

This paper proposes a stacked interleaved buck converter with an automatic current balancing capability using a series capacitor (SC). In addition, by magnetically coupling the two inductors, the inductor current ripple is effectively reduced. The inductor current ripple reduction contributed to improved efficiency and power density. Experimental results validate the proposed topology.
