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 mathemati...

Zusammenfassung: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.
