摘要
针对传统准Z源阻抗网络DC-DC升压变换器存在电压增益低和元件电压应力高的问题,提出一种新型准Z源高增益DC-DC升压变换器(HSQZSC).首先,分析HSQZSC变换器两种模态工作原理,并对其进行稳态分析和参数设计.其次,与现已提出的Z源变换器进行性能对比,表明HSQZSC变换器具有高电压增益和元件电压应力低的优势.然后,对其建立状态空间模型进行小信号分析、稳定性分析和控制器的设计.最后,搭建100 W实物样机,实验结果验证了HSQZSC变换器的可行性与有效性.
Abstract
A novel high step-up quasi-Z-source DC-DC boost converter(HSQZSC)is proposed in the article to address the shortcomings of low voltage gain and high component voltage stress in traditional quasi-Z-source impedance network DC-DC boost converters.Firstly,the working principles of the two modes of operation of the HSQZSC converter are analyzed,and their steady-state analysis and parameter design are conducted.Secondly,a performance comparison with the proposed Z-source converter shows that the HSQZSC converter has the advantages of high voltage gain and low component voltage stress.Then,a state-space model is established for small-signal analysis,stability analysis,and controller design.Finally,a 100 W physical prototype is built,and experimental results verify the feasibility and effectiveness of the HSQZSC converter.
