摘要：
This paper proposes a fundamental voltage equivalent principle-based over-modulation algorithm to increase the maximum output torque for induction motor (IM) field-weakening control. By using the proposed approach, the hexagon voltage vector can be achieved, leading to optimized dc-link voltage utilization. Besides, the phase delay in voltage vector is avoided by using a circle-type reference. To further eliminate the influence of the harmonics on the current regulator, a Butterworth filter is adopted to filter out the harmonic components in the feedback current. The experimental results verify the effectiveness of the algorithm.
