Abstract: A Direct Torque control at constant switching frequency is presented in this work. Torque and Stator Flux vector control during normal and overmodulation region is achieved by using the proposed algorithm. Complete exploitation of the inverter voltage and current capability for operation in the field-weakening range gives a faster dynamic response and average steady state control of torque for speeds as high as four times the base speed.
