A Novel Thirteen-Level Inverter Using a Single DC Source

Youssef Ounejjar, Lahcen Bejjit

A novel thirteen-level inverter is proposed in this paper. It is based on the PUC inverter; however, whereas the latter makes uses of separate DC sources, the proposed inverter is constituted of two series-connected capacitors. This offers the benefit of combining advantages of NPC and PUC inverters. It, also, allows the possibility of generating thirteen voltage levels while using a single DC source. The proposed inverter has, hence, a reduced impact on loads systems resulting on a good energetic efficiency while using an optimized count of switches and passive components. A hysteresis control technique is designed to draw a nearly sinusoidal load current and voltage which allows avoiding use of expensive and bulky filters. The whole system was performed in Matlab Simulink environment. The proposed system was verified through simulation.
