为了克服传统Z源／准Z源拓扑升压能力不足、无法实现输入输出侧电气隔离等缺陷，提出了两种隔离型开关电感准Z源逆变器，利用隔离变压器代替传统准Z源拓扑中的一个电感，使电路具有升降压的功能。探讨了电路的工作原理及控制方法，仿真及实验结果证明了拓扑的有效性。

In order to overcome the disadvantages of traditional Quasi-Z-source and Z-source inverter, such as limited boost ability, unable to realize the electrical isolation between input and output, and so on.Thus two isolated switched-inductor quasi Z-source inverters with buck and boost ability are proposed in this paper, where an isolated transformer is used to replace an inductor in traditional quasi Z-source topology.The circuit operation principle and control strategy are discussed in detail, and the simulation and experimental results verify the effectiveness of the pro-posed topology.
