Research on Three Phase Reversible PWM Rectifier Based on Vector Control

通过三相PWM可逆整流器各矢量在空间的坐标变换,导出PWM可逆整流器有关控制方程,在此基础上结合空间矢量调制(SVPWM)的算法,提出一种便于数字实现的PWM可逆整流器的双闭环控制算法,并以TMS320F240为控制核心设计制作了PWM可逆整流器的实验装置,实验结果验证了这种新型控制方法的有效性。

The paper presents a suitable digital algorithm for the PWM rectifier, on the basis of coordinate analyzing theory and the space vector pulse width modulation method. The rectifier with DSP（TMS320F240） based full digital control on the double closed-loop control metlod is developed. The experimental results prove that it is practical and correct,
