A Review Article on PWM Inverter and Z-Source Inverter for Induction Motor

摘要

This paper presents the study and analysis of the development of an inverter specifically PWM-based voltage source inverter and Z-source inverter that supplies variable frequency and variable voltage and is used for speed control in an induction motor. In this paper, the review work of the already presented paper has been done. The sinusoidal PWM method and space vector PWM method used in VSI fed induction motor are studied, and also, the comparison between them is studied and analyzed. These methods have advantages in terms of harmonic reduction. The space vector PWM method reduces current and voltage harmonics more than the sinusoidal PWM method. Also, using a Z-source inverter increases the efficiency which has also been described and studied in this paper. Utilizing this method with a maximum boost control switching method results in a faster rate of achieving a steady speed.
