Development of a Stand-Alone Connected PV System Based on Packe U Cell Inverter

In this paper, we investigate a competitive Multilevel Inverter (MLI) named by Packed U Cell (PUC). This converter is capable to generate more levels with fewer components compared with existing MLI topologies. The system consists of a PV arrays supply connected to a single-phase PUC5 inverter. A boost converter is employed to extract the Maximum Power (MPP) controlled by an MPP tracking (MPPT) algorithm. Then, A nonlinear control strategy with Pulse Width Modulation (PWM) is used to control the 5-level PUC (PUC5) to ensure good tracking and high-quality convention. Some simulations were performed in MATLAB/SIMULINK to demonstrate the effectiveness of this topology with the proposed control scheme.
