Abstract
<p>This paper proposes a field-weakening control strategy to optimize the torque production and motor efficiency of a four-switch three-phase inverter-fed induction motor drive in the high-speed region. A method to control the torque component current (Iq) and the flux component current (Id) of the field-weakening region is proposed. The feasibility of the proposed control strategy is verified through a simulation and validated experimentally. The results show that the speed-torque characteristics and the motor efficiency are improved in the high-speed region.</p>
