| 摘 要： | 永磁同步电机无电解电容驱动系统因其成本与寿命的优势,在白色家电领域逐步得到广泛的应用。然而,由于使用小容量的薄膜电容取代大容量的电解电容,母线电压会以两倍工频波动,在母线电压处于波谷时,逆变器输出电压容易饱和,导致控制性能恶化,网侧电流畸变。因此,提出了一种基于高功率因数控制的转矩控制环和电压矢量修正策略,能够有效提升网侧功率因数,抑制网侧电流谐波并符合IEC 6100032标准。该算法的有效性通过仿真得以验证。

| Abstract: | Permanent magnet synchronous motor (PMSM) drive system without electrolytic capacitor was widely used in the field of white home appliance owing to its cost and longevity advantages. However, small film capacitor was utilized to replace the large volume electrolytic capacitor so that the DC bus voltage fluctuated with twice the frequency of AC source voltage. The inverter ouput voltage was saturated and the control performance was deteriorated when the DC bus voltage dropped near zero periodically, and the grid input current was distorted and the power factor was low. A motor torque control loop and an inverter output voltage modification method based on high power factor control were proposed, which could reduce the grid input current harmonics and meet the guideline of IEC 6100032. The effectiveness of the proposed method was verified through simulation. |
