This paper presents the performance analysis of Quasi-Z-Source Inverter (QZSI) using Model Predictive Controller (MPC) for Photovoltaic (PV) generation system. This QZSI employs a unique impedance network to couple the inverter main circuit to the power source. It’s providing unique features that cannot be obtained in the conventional Voltage Source Inverter (VSI) and Current Source Inverter (CSI). The main aim of MPC is predicting the future values of output variables using a dynamic model of the process. Using a cost function optimization the error should be minimized and the best switching state is selected. QZSI inductor current and capacitor voltage are changed based on the same cost function. The MATLAB simulation results show the performance analysis of QZSI using MPC.
