A review of Direct Power Control Technologies for Three-Phase Voltage PWM Rectifiers

Abstract

This article reviews the direct power control methods of three-phase voltage-type PWM rectifiers, including those based on virtual flux linkage (VF-DPC), model prediction (MP-DPC), and dual switch table. First, the basic topology of the three-phase voltage-type PWM rectifier is introduced, and its key role in the energy conversion process is explained. Subsequently, the implementation mechanisms, advantages and disadvantages of various direct power control strategies and their performance in practical applications are comparatively analyzed. Finally, the article looks forward to future development trends in three-phase voltage-type PWM rectifier direct power control technology, and points out directions for further research, including algorithm optimization, hardware implementation, and broader application promotion.
