A Fuzzy-Logic-Based Controller for Three-Phase PWM Rectifier With Unity Power Factor Operation
In this paper, direct power control (DPC) of three-phase PWM rectifiers based on fuzzy logic controller is presented, without line voltage sensors. The control technique is built upon the ideas of the well known direct torque control (DTC) for induction motors. The instantaneous active and reactive powers, directly controlled by selecting the optimum state of the converter, are used as the PWM ...

متن کاملComparison of PI and Fuzzy logic DC-Link Voltage Controller for DPC PWM-Rectifier
This paper treats direct power control (DPC) for three-phase PWM rectifiers using a new switching table, without line voltage sensors and the fuzzy logic theory. The instantaneous active and reactive powers, directly controlled by selecting the optimum state of the converter, are used as the PWM control variables instead of the phase line currents being used. These strategies are used to elimin...
