Abstract
This paper proposes a new hybrid 9-level inverter topology for single phase grid connected PV systems. This inverter has combined the features of neutral point clamped (NPC), flying capacitor (FC) multilevel inverters (MLI) and coupled inductor phenomenon. It produces 9-level output voltage with minimum number of power components, which improves the efficiency of the system and reduces the cost as well. Another advantage of this topology is that there is no need of additional balancing circuit to regulate the input DC capacitors and auxiliary capacitor. The proposed topology is investigated through MATLAB simulations for 1000W system and all the results are presented.
