| 摘 要： | 为了研究准Z源逆变器的内在特性及Z源网络不同组件容量对逆变器动态性能的影响, 对准Z源逆变器在电流连续模式下进行暂态建模与分析.采用信号流图的小信号建模方法对该逆变器的DC侧建模,获得控制与输出的传递函数,为准Z源逆变器设计控制策略提供理论依据.发现传递函数存在右半平面零点,说明逆变器具有非最小相位输出的特性.利用控制...

| Abstract: | In order to investigate the inherit characters of a quasi-Z-source inverter(qZSI) and the influence of Z-source passive component's volume on dynamic performance,the transient modeling and analysis of the qZSI in continuous conduction mode are presented.The control-capacitor-voltage transfer function was obtained by deriving the ac small-signal model at dc side,and this was the theoretical basis of designing the controller of inverter.At the same time,a right-half-plane(RHP) zero was found in the derived tr... |
