- The paper presents an analysis of a hybrid 13-level inverter, which consists of three cascaded H-bridges per phase. Each H-bridge produces 5-level voltages. The proposed approach can be extended to any desired number of levels. Extensive simulation results of the proposed inverter are presented. Several aspects as total harmonic distortion factor of the inverter output currents, and voltages, harmonic content, frequency spectrum distribution, and switching power losses are studied to determine an optimal operation point of the inverter. The simulations are validated by hardware-in-the-loop experimental results.
