摘要：Numerous topologies of the multilevel inverter (MLI) are reported in the literature to reduce the number of switches for getting higher levels of output. This paper puts forward a novel asymmetrical MLI topology, in which the number of switches is reduced, compared to other topologies of MLI. Here, the performance of 9-level inverter is analysed using two types of the level shifted sinusoidal pulse width modulation techniques (SPWM) named alternate phase opposition disposition (APOD) SPWM and carrier overlapping (CO) SPWM. The performance analysis of the MLI is done using MATLAB/Simulink platform. Further, real-time implementation of the same has been carried out using Typhoon HIL 402 emulator. The comparative study of variations in total harmonic distortion (THD) of the output voltage and current of 9-level MLI under various conditions is presented in this paper to validate the proposed topology.
