In this article, a novel cascade model-predictive control for a three-phase unity power factor rectifier is presented. Unlike the traditional control techniques for rectifiers, the proposed method uses a cascade dual-model-predictive control for the inner and outer control loops. The three-phase currents of the rectifier are controlled with the inner control loop, while the desired output voltage is achieved with the outer control loop. In this proposal, the output power is used as a feedforward to enhance the transient dynamics of the output dc voltage. Several advantages can be highlighted such as a fixed switching frequency, and output voltage variations are avoided when a sudden change in the load or a voltage sag appears. The overall control proposal has been fully integrated into a digital signal processor. Selected experimental results are introduced to validate the theoretical contributions of this article.

三相单位功率因数整流器的双回路连续控制集模型预测控制

在本文中，提出了一种用于三相单位功率因数整流器的新型级联模型预测控制。与传统的整流器控制技术不同，所提出的方法对内部和外部控制回路使用级联双模型预测控制。整流器的三相电流由内部控制回路控制，而所需的输出电压由外部控制回路实现。在该提议中，输出功率用作前馈以增强输出直流电压的瞬态动态。可以突出几个优点，例如固定的开关频率，并且在负载突然变化或电压骤降出现时可以避免输出电压变化。整体控制方案已完全集成到数字信号处理器中。
