Direct Power Control of PWM Rectifiers Based on Virtual Flux
In this paper, direct power control based on the virtual flux (VF-DPC) of the three-phase voltage-type PWM rectifier is presented and the formation mechanism of the switching table is analyzed. In Matlab /simulink environment the model of the VF-DPC system is established.The simulink results show that the system has good dynamic response and a good way to achieve active power and reactive power control,while ensuring the input side of the unity power factor control.Compared with the existing current control strategy,VF-DPC system without complicated algorithms and PWM modulation block can achieve higher power factor and low harmonic disturbance (THD).
