Constant frequency torque controllerbased direct torque control (CFTC-DTC) is emerging as a powerful control strategy for a high

performance control of alternating-current motor drives. Compared to DTC, the CFTC-DTC has less torque and flux ripples with a

fixed switching frequency. Nevertheless, it has a limitation of the torque-loop bandwidth, as it uses the sampling frequency from a

digital signal processor (DSP) to generate a triangular-based carrier. The switching frequency of the control system is determined by

the carrier frequency of the CFTC. The frequency limitation of CFTC leads to sector-flux droop, which causes a distortion in the motor

phase current and aggravation in the torque and speed waveforms at low speed regions. In this paper, we propose a modification

of the frequency carriers of the CFTC-DTC of induction motors to increase the switching frequency and torque loop bandwidth by

replacing the triangular-carrier-based waveform with a ramp-carrier-based waveform. The proposed method is verified by simulation

and experimental results showing its excellent performances in steady- and transient-state operations.
