z源逆变器作为一种单级降压逆变器拓扑在许多研究人员中得到了广泛的应用。然而，它的升压能力可能是有限的，因此它可能不适合一些应用需要非常高的升压要求级联其他dc-dc升压转换器。这可能会降低效率，并且需要更多的传感器来控制增加的新阶段。本文提出了一种新的扩展升压准ZSI族，以填补ZSI发展中留下的研究空白。这些新的拓扑可以使用为原始ZSI开发的相同调制方法进行操作。此外，它们具有与原始ZSI相同数量的活动开关，保留了ZSI的单级性质。本文对所提出的拓扑结构进行了稳态分析，并利用Matlab/Simulink中的仿真结果验证了其性能。此外，它们还通过实验室开发的原型得到的结果进行了实验验证。
The Z-source inverter has gained popularity as a single-stage buck-boost inverter topology among many researchers. However, its boosting capability could be limited and therefore it may not be suitable for some applications requiring very high boost demanding of cascading other dc-dc boost converters. This could lose the efficiency and demand more sensing for controlling the added new stages. This paper is proposing a new family of extended boost quasi ZSI to fill the research gap left in the development of ZSI. These new topologies can be operated with same modulation methods that were developed for original ZSI. Also they have the same number of active switches as original ZSI preserving the singlestage nature of ZSI. Proposed topologies are analyzed in the steady state and their performances are validated using simulated results obtained in Matlab/Simulink. Furthermore they are experimentally validated with results obtained from a prototype developed in the laboratory.
