Abstract

According to the neutral-point balance problem of three-phase three-level pulse-width modulation （PWM） rectifier, this paper proposes a improved droop control. Firstly, based on the space vector control, we analyze the main circuit topology of the three-phase three-level PWM rectifier and establish its mathematical model. Then, we realize the dq decoupling of feedback voltage and current, and introduce a droop coefficient to correct the feedback voltage；so then, the tracking performance of the output voltage is improved, and fast unit power factor control and fast transient response are achieved. Finally, through Matlab/Simulink simulation, it is proved that the control strategy has good dynamic performance and static performance.
