一种改进型Z源逆变器

传统Z源逆变器存在诸如输入电流不连续，启动冲击电流大，电容应力大等缺陷，为解决上述Z源所存在的不足，研究一种新的Z源电路拓扑。在保持同样的升压情况下，该改进型拓扑电容应力明显减小，冲击电流得到抑制。简要对比二者拓扑下的工作原理，并通过 saber 软件对单相 Z 源逆变器进行仿真，仿真结果验证了改进型Z源拓扑性能的优越性。

A Modified Z Source Inverter

The traditional Z source inverter exists the shortcomings such as the input current being discontinuous, the impact current at start being large, and big capacitance stress defects. And in order to overcome the shortage of the Z source inverter, a new source of Z circuit topology was studied. Under the same boost in cases, the improved topology capacitance stress significantly reduced, and the impulse current was suppressed. Their topology of the working principle was briefly compared, and single-phase Z source inverter was simulated through the saber software. The simulation results demonstrate the superiority of the performance of the modified Z source topology .
