| 摘 要： | 为解决传统准Z源逆变器升压能力不足的问题,文章设计了一种改进型高增益准Z源逆变器,该逆变器在传统准Z源逆变器的基础上,将两个电感分别用升压单元和开关电感代替,且将二极管的位置与传统逆变器位置互换。与传统的准Z源逆变器相比,该逆变器提高了升压能力,扩大了调制因子范围。仿真分析和理论验证证明了该新型准Z源逆变器拓扑结构的准确性与有效性。

| Abstract: | In order to solve the shortage of the boosting capability of the traditional quasi-Z source inverter,an improved high gain quasi-Z source inverter is proposed.The improved high-gain quasi-Z source inverter replaces the two inductors with the boosting unit and the switching inductor and replaces the position of the diode with the traditional inverter position based on the conventional quasi-Z source inverter.Compared with the traditional quasi-Z source inverter,the inverter has the advantages of improved boosting capability and wider application range.The range of modulation factors is expanded to ensure good quality of the output power.Simulation analysis and theoretical verification prove the accuracy and effectiveness of this new quasi-Z source inverter topology. |
