Abstract
this paper presents Model Predictive Control (MPC) to tie three-phase quasi Z-Source Inverter (qZSI) to the utility grid. Regularly, to control the capacitor voltage in qZSI based on MPC, the inductor current is the key factor. Here, the proposed algorithm has the features of decreasing the number of sensors where the inductor current sensor is removed to improve the cost and foot print of the control implementation. The value of the inductor current is defined according to an estimation methodology that uses the previous optimized switching state and the capacitor voltage during this state. In addition, the proposed algorithm has the features of decreasing the number of iteration to improve the response of the control. The proposed technique has been explained in details over theoretical analysis and confirmed with the simulation results utilizing MATLAB/SIMULINK software. Additionally, experimental validation has been presented using the digital signal processor F28335 with hardware setup.
