Enhacing the Power Quality and Performance of Induction Motor Drive [ READ ]
Sayyad Naimuddin, Komal Ambhorkar, Dr. D. R.Tutakne
VVVF drives are widely used for speed control of induction motor in many Industries. Phase angle voltage controlled technique is mostly implied for soft start of induction motor however it suffers from drawbacks like retardation of the firing angle which causes lagging power factor at the input side especially at lower speed. In this paper, a new variable voltage control technique is proposed which uses only two high frequency PWM controllable switches for speed control of Induction motor .This method will be suitable for fan, pump and blower load coupled to a single phase induction motor which is used in almost all industries. The advantages of proposed method are its high power factor, high efficiency and less power consumption.The control technique used is easy and convenient. The technique used is economical and can be used in domestic and industrial Applications.
