Abstract

Multi-level inverter has emerged as an important topology in the area of high-power-medium voltage energy control applications due to its several advantages such as its good harmonic rejection capability, better output voltage with reduced ripple, reduction of voltage ratings of the power semiconductor switching devices and also the reduced electro-magnetic interference problems, etc. This paper presents the torque ripple minimization and the performance under different operating conditions (dynamic and steady state) of indirect vector-controlled high-power fed induction motor driven by three-level inverter with the low switching frequency 0.5­1 kHz. It also presents simplified space-vector modulation method for a three-level inverter. The torque ripple of induction motor drive fed with a two-level inverter and a three-level inverter is compared. The total harmonic distortion values of inverter line-to-line voltages and induction motor phase current values are also compared using two-level inverter and three-level inverter.
