Abstract
This paper focused on reviewing the main types of topologies and control strategies employed for the operation of multilevel inverter. Advantages and disadvantages of the topologies and the control techniques in relation to one another are equally reviewed. Recent proposed methods employed to improve the harmonic performance, reduce electromagnetic interference (EMI), lower stress on the power switches, eliminate DC link voltage imbalance and simplify the pulse width modulation control algorithms are fully reviewed. Selective harmonic elimination modulation technique is used in generating the 11-level of output voltage. It is aimed at reducing the total harmonic distortion as low as possible.
