A soft‐switching inverting high step‐down converter with a pair of coupled inductors and self‐driven synchronous rectifier

Abstract In this paper, a non‐isolated coupled‐inductor high step‐down converter with extended duty cycle is proposed, which operates under discontinuous conduction mode. The soft‐switching condition is provided for all the switches and diodes, which results in the reduction of the switching losses,...
