Aiming at the low DC boost capacity, serious starting-up inrush current and low DC voltage utilization of traditional Z-source inverter, an improved topology of Z-source inverter is proposed.

针对传统Z源逆变器的直流升压因子较小、启动冲击严重、直流侧的电压利用率较低等缺点，提出了一种改进型的Z源逆变器拓扑。

It is showed that this transformer has the advantages of boosting, rejecting the negative sequence current, increasing the output capacity and raising the capacity utilization ratio.

结果表明，该变压器具有增压、抑制负序电流、增大输出容量和提高容量利用率等优点。

As a result, very little, if any, excess liquidity spilled over into imprudent hands as indicated by the current low inflation and low capacity utilization.
