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.
