A Family of Y-Source DC/DC Converter Based on Switched Inductor

A novel family of high-gain dc/dc converters based on Y-source impedance network is proposed in this paper providing novel solutions to high voltage gain applications, such as photovoltaic and fuel cell systems. Proposed converters combine Y-source with boost modules resulting in strong boost ability, continuous input current, and inrush current suppression. Design flexibility and joint earthing of input and source are inherited from conventional Y-source. Working principles are presented and accurate steady-state analysis is conducted by mathematical derivations, moreover, comparisons among proposed converters and other impedance networks highlight their excellent performance. Experimental results show good agreement with theoretical analysis and the high feasibility of the proposed converters.
