具有无失真电压饱和与抗饱和功能的多频电流控制有效限流方法

In three-phase converters, it is frequently important to control current components other than the positive-sequence fundamental. Adequate voltage saturation and antiwindup (VSA) should also be included to prevent malfunction under output-voltage saturation due to, e.g., large voltage disturbances or dc-link-voltage reduction. A multifrequency VSA technique was recently proposed, based on modifyin...
