Abstract: This paper presents a high performance near state PWM (NSPWM) algorithm for the reduction of common mode voltage (CMV) in direct torque controlled induction motor drives. In the proposed algorithms, actual switching times are calculated using the concept of imaginary times. As the proposed method did not use sector identification and angle information, it reduces the complexity involved in conventional methods. To reduce CMV, in the proposed method active voltage vectors are used to program the output voltage. NSPWM algorithm utilizes three adjacent active voltage vectors for the composition of reference voltage vector. To validate the proposed algorithm, simulation studies have been carried out using MATLAB-Simulink and results have been presented.
