Abstract: Today in industry, 3-ph IM are being used at very wide scale. So its speed control according to specific requirement is very important. Also many times, 3-ph IM are to be operated with easily available 1-ph supply. For this, proposed mechanism of improving input power factor here is very efficient and reliable. At input terminal, high performance Two Stage Interleaved Power Factor Correction technique (IPFC) with boost topology operating with discontinuous current conduction is used. With this circuit, 3rd order harmonics can be eliminated upto completely from the input supply. Also it will help to achieve almost UNITY pf with rated power supply. With this type of 3-ph supply provided to the IM, Reactive power generation can be minimised which leads to efficient control over the wastage of Reactive power and use of Reactive power compensation techniques. So the overall cost of operating 3-ph IM can be minimised.
