Design of Five Level Inverter fed Induction Motor using Phase Shifted Carrier PWM technique
Multilevel inverter is an effective and practical solution for increasing power demand and reducing harmonics of
ac waveforms. Such inverters synthesize a desired output voltage from several levels of dc voltages as inputs. This paper
analyses the performance of five level inverter using phase shifted carrier PWM technique. It has been found that this
technique reduces the switching losses and total harmonic distortion. The performance being analyzed by the
SimPowerSystems in Matlab-Simulink and hardware being prepared using IGBT as a switching device and a microcontroller
for Gate pulses.
