Abstract: This paper presents a single-phase efficient and generalized basic topology that is adaptable for multilevel inverters. The proposed structure is run by a switching pattern of the power switches i.e, subharmonic pulse width modulation (SHPWM) or comparison of triangular carrier high-frequency waveforms with a sinusoidal reference waveform. This chapter shows an asymmetric modulation method (AMM) hybrid modulation inverter with its working and performance verified through the simulation studies conducted in MATLAB Simulink software. A test for crucial voltage identification has also been carried out that recognizes the most important voltage source that must be maintained constant, else it would adversely effect the circuit’s operation.
