ABSTRACT: Multilevel inverters have gained much attention for its operation
involving applications ranging values of high power rating. This paper proposes
a switching topology for asymmetric multilevel inverter utilizing less number
of power electronics components. When the number of the output level increases,
it requires more switching states and eventually the number of switching components.
The increased number of switches results in higher switching losses which may
lead to power loss, and reduction of efficiency of the overall conversion
system. The salient feature of this proposed topology is that the module can be
used as a sub multiple level structure and can be extended for any number of
level with minimal increase in the switching components.
