reduce their overall reliability and efficiency. On the other
hand, an inverter with a lower number of output voltage
levels requires a large LC output filter to decrease the
motor winding insulation stress. The challenge is to reduce
waveform distortions and total harmonic distortion when
the lower switching frequency is used, to ensure high
power quality, and to allow fast transient operations. The
switching loss due to the fast transition is an important

issue that should be considered in MV drives. The maximum and minimum modulation depth and a power factor
range between 1 and −1 are the critical operating points
of MIs. When applying continuous modulation methods,
some switching devices reach their maximum allowable junction temperature, while other switches remain
much cooler. Unbalanced distributions of junction temperatures depend on the type of modulation method used.
