摘　　要：针对传统的准Z源DC-DC变换器存在的输出电压有限、稳定性较差、增益较低等问题,提出了一种新型的准Z源DC-DC变换器的电路拓扑,并对该拓扑的构成及工作原理进行理论分析。与传统的准Z源DC-DC变换器的拓扑结构相比较,表明新型的拓扑具有升压比大、可靠性高等优点。运用MATLAB/Simulink软件对电路进行仿真,验证了理论分析的正确性。最后,通过搭建实验电路,验证了新型电路拓扑的可行性及实用性。Aiming at the shortages of traditional quasi-Z-source DC-DC converters such as limited output voltage,poor stability,low voltage gain and so on,a new quasi-Z-source DC-DC converter topology is presented,and the structure and working principle of the topology are analyzed theoretically.Compared with the traditional quasi-Z-source DC-DC converter topology,the results show that the new topology has the advantages of large boost ratio,high reliability,and so on.The circuit is simulated by MATLAB/Simulink software,and the correctness of the theoretical analysis is verified.Finally,the feasibility and practicability of the new circuit topology are verified by experiments.
