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.
