Abstract: The paper presents dSPACE controlled Induction motor drive fed through Discontinuous pulse width modulation (DPWM) algorithm based voltage source inverter. Two important performance measuring factors harmonic distortion in line current and dc bus utilization of the inverter can be improved with Discontinuous PWM approach in comparison with the popular conventional space vector (CSVPWM) approach; the paper contemplates on the implementation of DPWM algorithm for pulse generation which in turn are fed to intelligent power module that feeds the motor drive through DS1104 PPC603e / 250 MHz control desk. The results conclude the successful implementation of dSPACE Controlled induction motor drive. To validate the proposed work, numerical simulation including the experimental results is presented.
