Efficacy of Multi Inverter Fed Induction Motor
View through CrossRef
Abstract
Copious research has been ongoing in the field of inverter fed induction motor drives. The main challenge in designing Pulse width Modulation (PWM) fed induction motor drives is to concomitantly reduce switching losses and Total Harmonic Distortion (THD) occurring in inverter. PWM voltage source multi inverter is analyzed for applications of drives for achieving benefits of reduction in switching losses, reducing filter size, low ripple current at output and high efficiency over wide range of operation. In this letter, multi inverter prototype consists of dual three phase PWM full bridge from separate source operated in tandem with phase shift. This topology improves the performance of drive and can be used for high power rating drives. The proposed approach is verified with dual inverter fed 5 hp induction motor experimentally.
