A New Vector Control for Induction Motor Drives in Full Block Mode of Inverters

Abstract

This paper presents a new vector control for induction motor drives in full block mode, so called One-Pulse mode, of inverters. For traction drives the inverter usually operates in this mode in a high speed region. The amplitude of voltage vector is restricted constant in the mode. The conventional vector control is not applicable as it requires controllability of both the amplitude and the phase of the voltage vector for all time. The proposed scheme provides quick torque response even in the One-Pulse mode. Experimental results are shown to validate the effectiveness of the control.
