چکیده
This paper presents simplified space vector pulse width modulation (SVPWM) based vector controlled induction motor drive. The conventional SVPWM algorithm constructs the required voltage vector in the average sense by using active and zero voltage vectors. Moreover, complexity involved in conventional SVPWM algorithm is more. Whereas, the proposed SVPWM algorithm calculates the switching times using the concept of imaginary switching times. The proposed algorithm does not need the calculation of sector and angle information. To validate the proposed algorithm, simulation studies have been carried out on vector controlled induction motor drive and the results are presented in this paper.
