Split-source inverter

Single-stage DC-AC power converters are recently gaining higher popularity due to their features in terms of size, cost, weight, and complexity of the whole system. Different topologies exist, where the Z-source inverter, the buck-boost voltage source inverter, and the Y-source inverter are the common topologies. This paper proposes another single-stage DC-AC power converter, called the split-source inverter. The proposed topology has some merits over the other topologies, the main being the possibility to use the same modulation schemes of the conventional voltage source inverter without any modification. The operation of the split-source inverter is studied and analyzed in this paper then verified using MATLAB/Simulink models. Finally a small-scale prototype is used to confirm the functionality of the proposed idea.
