Abstract

A hybrid advanced bus clamping space vector PWM (ABCSVPWM)-based hysteresis current-controlled (HCC) voltage-sourced two-level inverter (VSI)-fed induction motor (IM) drive with a nearly constant switching frequency for improved peak-to-peak ripple torque is proposed in this paper. Online computation of the current error boundary from the sampled magnitudes of the reference phase voltages reduces the complexity and merges the advantages of current-controlled and voltage-controlled drives. The hybrid SVPWM applies advanced bus clamping sequences along with the conventional one and improves the torque ripple reduction capability, which enhances the performance. The phase voltage harmonic spectrum of the proposed drive is similar to that of voltage-controlled drives. An extensive analysis of the proposed drive is performed using MATLAB-Simulink for the transient and steady state responses of the drive. The peak-to-peak torque ripple is significantly improved. The proposed controller is examined physically on a 2.2 kW, 3 φ, 415 V induction motor (IM) using the dSPACE platform.
