Four quadrant comparative evaluation of classical and ...

Abstract: This paper presents the comparative evaluation of the performance of two most popular control strategies for induction motor drives: Classical DTC and SVPWM-DTC (in all four quadrants of operation). Though Classical DTC is a simple method, it suffers from the disadvantages like variable & high switching frequency and high torque & current ripples in steady state.
