Abstract :
Analytical investigation of the current and electromagnetic torque ripples in the three-phase voltage source inverter fed induction motor drive under DC-link voltage pulsation is presented in this paper. The analytical expressions for the voltage and current space-vectors as a function of the DC-link voltage pulsation are derived. The analytical results are verified by the experiments.
