Abstract: Control systems and methods for starting an induction motor. The control system includes a plurality of wye switches, a plurality of delta switches, an AC power supply, and a soft-starter. The plurality of wye switches are connected between three phase stator windings of the induction motor such that closure of the plurality of wye switches causes the three phase stator windings to be connected in a wye connection. The plurality of delta switches are connected between the three phase stator windings such that closure of the plurality of delta switches causes the three phase stator windings to be connected in a delta configuration. The soft-starter is connected between three phase supply lines of the AC power supply and the three phase stator windings to control a supply of energy to the induction motor from the AC power supply.
