Abstrakt

This letter proposes a modified Y-source dc-dc converter, which features higher voltage-gains but lower voltage stresses on the components. Moreover, the proposed converter draws a continuous current from the dc input with much control flexibility (i.e., a wide range of adjustable duty cycles). Additionally, the coupled inductors have a low turns ratio, and the core saturation issue is avoided due to the dc-current-blocking capacitor. A detailed analysis of the proposed converter is provided, and the performance is benchmarked with selected coupled-inductors-based converters on various aspects. Experimental tests confirm the theoretical analysis.
