Ultra enhanced boost active switched based quasi Z-source inverter

Abstract

Abstract A high voltage gain inverter is essential requirements in high voltage applications. Z-source inverter (ZSI) is widely used for such a kind of applications. However, as the time goes on, new applications needed more boosting voltage from limited magnitude of voltage source. Hence effort is still continuing to increase the gain of ZSI but using optimum number of components. In most recently some ultra-gain topologies has been published in literature. The gain of these ultra-gain topologies is highest in contemporary times. However still there is a possibility to increase the voltage gain using same number of components that are already used in the ultra-gain topologies. In this manuscript, a topology has been proposed which provide higher voltage gain among the latest ultra-gain topologies. The proposed topology uses an active switch in the impedance network along with the components. The mathematical model along with the simulink and hardware model has been presented in the manuscript.
