摘要

本文提出了三相AC/DC变换器的两种直接功率控制方法——DPC算法。第一种方法DPC-SVM使用典型PI控制器和空间矢量调制器- svm。第二种方法是基于变换器数学模型的预测直接功率控制P-DPC。该控制在每个采样周期内选择电压矢量序列并计算其应用时刻，以使有功功率和无功功率的跟踪误差最小。仿真对比显示了两种控制策略在2khz开关频率下的性能。

Comparative study of two Direct Power Control algorithms for AC/DC converters

In this paper two different approaches of direct power control - DPC algorithms for three phase AC/DC converters have been presented. The first approach DPC-SVM uses typical PI controllers and space vector modulator-SVM. The second approach predictive direct power control P-DPC is based on mathematical model of converter. This control in every sampling period selects the voltage-vectorspsila sequences and computes their application instants in order to minimize tracking error of active and reactive power. Comparative simulations shows performance of both control strategies for 2 kHz switching frequency.
