A Novel Isolated Quazi Z-Source DC-DC Converter

Wenxu Si, Shan Li, Yan Chen, and Sen Cui
Abstract—The isolation quasi-Z-source converter is a new type of converter based on the conventional non isolated quasi-Z-source converter. Compared with the traditional converter into the isolation transformer, the topology has the advantages of simple structure, which not only reduces the number of switching devices, reduce costs, and reduce the voltage of each period in Z network stress, reduce the converter volume. The topology can in low voltage input, output arbitrary voltage value, further improve the energy transfer efficiency. Based on the analysis of the original converter, this paper introduces the structure of the isolated quasi Z source converter, and analyzes its working principle; secondly build isolation quasi-Z- source and the circuit simulation model of open loop simulation in PSIM software; the simulation results consistent with the theoretical value, verify the correctness of the theoretical analysis.

Index Terms—Isolation transformer, Quasi-Z-source, DC-DC converter, the simulation analysis.
