The paper suggests a 9-level inverter with quadruple boosting which it considers very useful for small-scale PV systems. The suggested circuit uses capacitors that are a self-balanced voltage without using an additional circuit or complicated control algorithms to balance the voltage of the capacitors. The circuit produces 9 levels with quadruple boost gain at the output terminals by using minimum components as compared with other recent topologies. The circuit analysis and modeling for each output level are described. The switching control strategy uses a simplistic logic control circuit relying on Pulse Width Modulation (PWM) is implemented to ensure balance voltage of capacitors. By the help of MATLAB/SIMULINK, the effectiveness and robustness of architecture are validated. Furthermore, a prototype for this topology is set up and tested in the laboratory using a DSPACE-1104 verifying the theoretical analysis. The experimental setup and hardware implementation are described. The theoretical and experimental results are investigated under various conditions illustrating excellent agreement between the theoretical and experimental endorses the targeted circuit. |
