Abstract
Many of the Adjustable speed drives are inverter based motor drives. There are various PWM techniques to control the inverter. This paper presents modified control strategy for five level asymmetrical dual inverter fed induction motor drive. The control method for the inverter improves the performance of the drive. The characteristics of the drive at different modulation indices were observed and found that at higher modulation index the total harmonic distortion of line currents is less. The time response of speed is better at modulation index greater than 0.75.The simulation based analysis and design is carried out in MATLABTM software.
