Abstract:-–This work proposes a new five-level inverter topology and modulation techniques are
proposed. In this proposed work compared to 5-level ANPC because the most similar topology,
this new topology needs 2 less switches at the price of a further capacitor and 6 diodes. However,
since the capacitors still see the switching frequency and their size remain a similar, it's expected
to reduce the inverter’s total value. Sensible loss distribution among switches will increase the
inverters rated power or offer higher switching frequency and smaller capacitor size. In this
proposed modulation technique to realize a good loss distribution, avoid direct series connection
of semiconductor devices, and keep the balanced operation of dc-link capacitors whereas keeping
the amount of costly parts like capacitors and switches low. The desired modulation strategy is
developed and also the operation of the projected topology is studied. Simulation results are
provided to verify the performance of the converter for medium voltage applications. . To
overcome the problem for the selective harmonic elimination methodology, the resultant
methodology is used to find all the solutions to the harmonic equations and also the active
harmonic elimination methodology is projected to eliminate any range of harmonics and may be
applied to the total modulation index vary for multilevel converters to satisfy the application
requirement
