Performance analysis of four-switch three-phase inverter-fed induction motor drive
TLDR
A four-switch three-phase inverter (FSTPI) is used, which reduces the cost of the inverter, the switching losses, the complexity of the control algorithms and the interface circuits to generate six PWM logic signals.Abstract:
This project deals with the performance evaluation of an induction motor fed from a four-switch three-phase inverter. Here, instead of using six-switch three-phase inverter (SSTPI), a four-switch three-phase inverter (FSTPI) is used. This reduces the cost of the inverter, the switching losses, the complexity of the control algorithms and the interface circuits to generate six PWM logic signals. Both PWM and SPWM techniques are implemented for switching. The performance of the motor and the Total Harmonic Distortion (THD) are compared in both of these techniques. Finally a comparison between the performance of induction motor fed from three phase six-switch based inverter and three phase four-switch based inverter is carried out.read more
