Abstract
Multilevel inverters (MLIs) is finding wide range of application in low, medium and high voltage system because of its capability to generate high-quality output voltage. However, this comes with the fact that number of components used in the converter is still high. As the number of components increases, the probability of fault occurring across any of this component increases, complexity of the circuit increases along with cost and increase gate driver circuit. This paper proposes the topology as symmetric single-phase enhanced T-type 7-level multilevel inverter. The proposed MLI has the capacity to self-balance, the capacitor voltage along with quality output. The proposed topology is verified in Matlab/Simulink and a comparative analysis is done with its previous models. The output across the load is verified by resistive, inductive resistive and asynchronous load.
