A Family of DC-DC Converters Based on Y-Source Impedance Network and Boost Module

A novel family of high-gain converters based on the Y-source impedance network is proposed in this paper, providing novel solutions to high voltage gain applications. Compared with the traditional improved Y-source topology, the proposed new topologies relocate the switch from the output side to the input side, which effectively reduces the stress of the switching device, and the topology combines different boost modules, which effectively improves the boost ability. In order to show the characteristics of the proposed topologies, the operating principles and analyses are given detailed in this paper. Experimental results verify the feasibility of the proposed converters.
