Abstract

Split-source inverters (SSIs) have been proposed as a potential candidate for high-gain single-stage dc-ac converters due to their superior merits over Z-source inverters. High-gain single-stage dc-ac converters are particularly useful for interfacing the PV modules with the AC power grids and loads. This paper uses the SSI to interface the PV modules with a single-phase grid. A simple control algorithm based on the model predictive control (FCS-MPC) without a pulse-width-modulator is proposed in this paper for the analyzed system. This algorithm. In this control strategy, the dc-link voltage is controlled by adjusting the grid current via the linear PI controller. Meanwhile, the FCS-MPC controls the grid current and the SSI input current. The SSI input current is controlled to track its reference value obtained by the MPPT algorithm. The implementation block diagram and the mathematical analysis of the proposed algorithm are presented. Finally, the entire system is simulated via MATLAB/Simulink to validate the proposed control scheme.
