The use of m

ltilevel invert

e
popular in recent
y
e
ars for high-

c
ati

Inverters
are power conver

composed by
an
array
of power
semi
conductor sources that when proper

connected
and controlled
can generat

variab

phase and
amplitude. This
stud

deals
with the comparison of a 7-level inverter
with a
9-leve
