基于三相电压型PWM整流器控制策略研究
Research on Control Strategy of Three-phase Voltage Source PWM Rectifier
摘要
Abstract
In the three-phase rectification process,a specific three-phase rectification topology is adopted,and a suitable control strategy is formulated according to the established mathematical model. In this way,the harmonics generated in the three-phase rectification process network are suppressed,and the sinusoidal fluctuation of the current-side current tracking voltage is realized. The working principle and mathematical model of the three-phase voltage-type PWM rectifier were analyzed,and improved the double closed-loop strategy,that is,the outer ring adopted sliding mode variable structure control,and the inner ring adopted predictive current control. Compared the control strategies,the current waveform and harmonic content on the grid side were analyzed. This control strategy was validated by building a simulation model in the Matlab/Simulink simulation platform,according to the grid-side voltage and current waveforms and the current harmonic content of the grid side,it is verified that the control strategy helps to suppress the current harmonics on the grid side and realize the sinusoidal fluctuation of the current tracking voltage.关键词
