Developed impedance-type power inverter

Switched Inductor and Switched capacitor Z source inverter are recent inverter topologies that have attracted many researchers as they have better boosting ability and near sinusoidal output wave forms. The technique of developed impedance type power inverter to enlarge voltage adjustability. The proposed inverter employs a unique impedance network to couple between main circuit and power source. This paper deals with analysis of developed impedance with/without shoot through state compared to classical Z-source inverter. Further new extended topologies are also proposed to increases the voltage boost inversion ability significantly. Only very short shoot through state is required which is beneficial to improving the output power quality. A detailed topology analysis and a generalized discussion are given. Both simulation and experimental result verify the analytical results.
