ABSTRACT

The requirements of a standard 3-phase Induction

Motor driven by a Voltage Source Inverter

studied. A ful I 3-phase Variable Speed Drive

and its controller have been designed, constructed

and tested. Gate Turn-Off Thyristors

used as the main switching elements in the Inverter

stage of the Drive. The drive requirements of

GTO's are studied in detai 1.
