摘　　要：从三相电压型PWM整流器电路结构与数学模型两方面入手,结合矢量控制技术,分析和研究了SVPWM控制的实现方法,并给出了电压、电流双闭环控制的设计参数。以TMS320LF2812为控制核心搭建实验平台,进行实验验证。实验结果表明,在该控制策略下,输入电压电流波形良好且相位相同,网侧输入电流的谐波含量低,系统性能优良。Compared with the traditional rectification way,three phase voltage PWM rectifier has the advantages of high power factor,low current harmonic and quick dynamic response.The structure and mathematical model were discussed in this paper.Based on the current tracking control,it gave the implementation of SVPWM control algorithm and design parameters of voltage-current double-loop control.A tested system based TMS320LF2812 was developed.The experimental results show that the input voltage and current waveform is perfect,the harmonic currents are low,and proves the excel1ent of this control tactics.
