Abstract

In this work, the performance of three phase PWM inverter fed PMSM drive is analyzed on the latest Matlab Simulink environment. Efforts have been made to reduce the distortion and harmonic contents in the current waveform. This has been done by varying parameters of the motor along with suitable variation in the parameters of PI controller. The motor was subjected to a step load. It has also been found that, by providing power supply in discrete form improved the current waveform and also reduced ripples in the torque. This observation paved way to sample the load at the same rate as of that of power supply. The authors have also calculated the Total Harmonic Distortion (THD) in the current waveform by Fast Fourier Transform and finally observed that due to different level of transient in each phase there is a variance in THD.
