Performance Analysis of Z - Source Inverter Topologies for Renewable Energy Sources and Fuel Cell Applications

In this paper, the three-phase, two-level Switched -Inductor based Z- Source Inverter (SL-ZSI) and SL based quasi-ZSI (SL-qZSI) are suggested for Renewable Energy Sources (RES) and fuel cell applications. The performance of both the topologies have been analyzed using sine reference based Simple Boost Control Technique (SBCT). The analytical and simulated results are compared with the traditional ZSI. A detailed analysis of topologies and generalized discussion is provided. The analytical and simulated results are verified using MATLAB/Simulink. Further, the proposed converters were simulated and compared with conventional ZSI using SBCT for various shoot through (K) and modulation indices (M).
