description | A high voltage gain inverter is a critical component of any high voltage power system, which feeds from a limited DC source. Numerous inventive solutions proposed to increase the boost factor. However, many of them have a large number of components and no short circuit immunity. While retaining the inherent characteristics of conventional quasi Z-source inverters (qZSI) with fewer components, this paper proposes two new active impedance source inverters based on qZSIs that utilize an additional active switch. In addition to the inherent benefits of qZSIs, the proposed topologies have a higher boost capability. They have an additional degree of freedom that allows the voltage ratio of the capacitors adjusted to any desired value without affecting the gain of the converter. They can also control the dc-link voltage without being fully dependent on the shoot-through time duration, resulting in a higher utilization factor for the dc-link. Additionally, the proposed topologies establish a common-ground connection between the input and output terminals, which is useful for some applications. In order to drive the inverters’ boost factor, the operation and steady-state analysis described. Furthermore, the comparative analysis done to illustrate the features of proposed topologies. Finally, a simulation and experimental analysis carried out to validate that the proposed inverters are feasible. |
