With the rapid development of new energy technology,the performance of DC-DC converters continuously increases.In this paper,a novel high-gain DC-DC converter is proposed,which is improved based on the quasi-Z-source topology.Owing to the use of the topology in which three capacitors discharge together to the load,a higher voltage gain is obtained while the voltage stress of capacitors is reduced.The proposed converter has advantages of the traditional quasi-Z-source converter such as simple control,continuous current and small current ripple.The working principle for this converter is analyzed.In addition,its performance was verified through simulation experiments and prototype experiments.
