Abstract |
|
|
| This paper presents the transformer-based multilevel inverter-fed induction motor drive. The development of new technology
of power electronic switches and control techniques for inverter-based speed control of induction motor has led to the usage of
induction motor in industrial and domestic applications. In this work, the stator winding of induction motor is fed through proposed
five-level transformer-based symmetrical inverter, which consists of unidirectional and bidirectional switches, mid-point transformer
and capacitors as voltage divider network to produce multilevel output voltage at the load side. The speed of the induction motor is
varied by changing supply voltage of an induction motor by adjusting width of the pulse width-modulated signal. A speed controller
has been implemented through fuzzy logic controller for performing closed loop operation of single phase induction motor drive. The
ability of fuzzy-based speed controller can reduce the undesirable sustained oscillations in speed of induction motor drive and also
provide better machine performance than conventional linear controller. The proposed controller performance of multilevel inverter-fed
induction motor drive system is validated through MATLAB simulink environment. |
