Abstract

In the motor systems, an increase of the power factor is conducive to the improvement of overload capacity and operation reliability. In this paper, a deadbeat strategy based on a power model is proposed. With the help of the power model, the reference power expression is derived, and the reference voltage expressed by the active power, reactive power and power regulation coefficient (m) is obtained. The method proposed in this paper realizes the traditional deadbeat strategy effect, and improves the power factor to some extent. Meanwhile, a new double-vector synthesis method is proposed. Under different reference voltages, different double-vector synthesis modes are directly selected. This results in good steady-state performance with low complexity. In performance comparisons, the proposed method surpasses the widely used duty-cycle double-vector method. Simulation and experimental results verify the effectiveness of the proposed algorithm.
