Space Vector Based High Performance Discontinuous Pulse Width Modulation Algorithms for VSI Fed AC Drive

M. Nayeemuddin, C. Srinivasa Rao

Abstract: This paper presents Space Vector based high performance Discontinuous Pulse width modulation (DPWM) algorithms for VSI fed Induction motor drive. To avoid the complexity due to angle calculation and sector identification involved in Conventional space vector pulse width modulation (CSVPWM), the proposed algorithms use the concept of Imaginary Switching times and a constant variable and modulation phase angle are used to generate modulating waveforms. The proposed algorithms results in reduced current ripple over CSVPWM. To validate the proposed methods, simulation is carried on V/f controlled Induction Motor drive in MATLAB/SIMULINK environment and the results have been presented.

Keywords: CSVPWM, DPWM, Imaginary Switching times, V/f control
