摘要

In this paper, the Z-source inverter voltage gain is increased by using switched-inductor structure. In the proposed structure, the diodes of switched-inductor are substituted by the capacitors; therefore, the proposed inverter can be named the embedded switched-capacitor-inductor Z-source inverter. The higher voltage gain per smaller duty cycle ratio is the advantage of the proposed structure in comparison with the conventional structure. Another advantage of the proposed inverter is that the voltage stress in Z-source network is less. Besides, in the second proposed inverter, to reduce the peak and ripple of source current, the dc sources are placed in switched-inductor structure. The renewable energy sources such as solar panels can be used as dc sources. To show the performance of the proposed inventers, the laboratory prototypes with 30V(dc) input voltage are used. The correctness operations of the proposed inverters are proved by simulation results (PSCAD/EMTDC) and laboratory test.
