介绍了三相电压型整流器的原理,空间矢量PWM算法(SVPWM)理论,采用电压、电流双闭环控制策略,利用遗传算法求解控制系统的参数,数字信号处理器DSP TMS320F2812来实现三相PWM整流器空间矢量的全数字控制,实现大功率可控整流电路的控制,实验表明系统稳定性和抗干扰性都明显提高,通过实验结果证实了以上设计方法的可行性。

The three-phase voltage-type PWM rectifier theory and the space vector PWM control algorithm （SVPWM） theory were described in this article. The voltage and current double closed loop control strategy was applied, the genetic algorithm was used to calculate the control system parameters, and DSP TMS320F2812 was adopted to achieve the three-phase space vector PWM rectifier＇s digital control and achieve the high power controlled rectifier＇s control. Finally, the results show that system stability and noise immunity are markedly improved. The above experimental results confirm the feasibility of the design method.
