Abstract
The Quazi Z-Source Inverter (QZSI) is utilized instead the traditional ZSI in PV applications; because its advantages over the traditional ZSI. This QZSI is controlled using two-stage control scheme which is inspired from the two-stage control Module Integrated Converters (MICs). The two-stage control structure is based on a derived SSM of the QZSI impedance network. A Modified Direct Incremental Conductance Maximum Power Point Tracking (MDIC-MPPT) algorithm is used to overcome the problems associated with the existing techniques.The obtained results based on SSM analysis are compared to those obtained using different Particle Swarm Optimization (PSO) techniques
