The efficiency of a motor drive combined with an inverter increases by exploiting the maximum voltage level that can be provided by the inverter. This paper presents a novel control strategy for the induction motor in the field-weakening range. The inverter's voltage margin is utilised using only the variation of the argument of the stator voltage vector and avoiding any zero voltage vectors in steady state operation.
