Comparison of Two Level & Three Level Five Phase Inverter
Multilevel inverter has gained much attention in recent years due to its advantages in lower switching loss better electromagnetic compatibility, higher voltage sustainability and lower harmonics. In recent researches it is found that by employing a higher number of phases one can reduce the amplitude and increase the frequency of torque pulsations in the drive. This paper proposes a difference between 3-level inverter and 2-level inverter. However, increasing the number of phases reduces Total Harmonic Distortion(THD).
