Novel Symmetric/Asymmetric Generalized Multilevel Inverter Based on T-Type With Reduced Switch Count

A sinusoidal voltage with excellent quality and total harmonic distortion (THD) is produced using multi-level inverters (MLI). The idea of MLI was introduced by some traditional designs, but their drawbacks—such as the quantity of DC sources and switching components and their low THD—made the inverter more expensive and larger. With fewer switches, the suggested MLI can get around these restrictions. The suggested structure contains less switching devices, drivers, and total standing voltage (TSV) as compared to MLI architectures. The T-Type inverter has been enhanced in the suggested construction. An enhanced H -bridge and two T-type inverters are combined in the suggested configuration. Two symmetrical diodes make up the T-type inverter that makes up the suggested configuration. To prove the superiority of the suggested structure, we compare it with different structures. Lastly, we use nearest level modulation (NLM) to show the simulation results under different loads.
