| 摘 要： | 为抑制三相电压型PWM整流器的直流输出电压谐波,根据功率平衡原理,提出了一种基于正负序控制器的不平衡控制策略.该策略由瞬时功率相等的原则,推导出输入电流正负序分量指令值,构建正负序两个控制器分别对电流正负序分量进行调节,采用普通的前馈解耦和PI控制器就可获得良好的控制性能.仿真结果表明提出的控制策略能够很好地抑制直流输出电压谐波. |

| Abstract: | A unbalanced control strategy of positive and negative controllers for three phase voltage source PWM rectifier based on power-equation principle was proposed aim at suppressing the harmonic of DC output voltage.The strategy calculates the commands of positive and negative currents using the equation principle of instantaneous power,and designs positive and negative controllers to regulate the positive and negative currents separately.By decoupling feed-forward and PI controller,this strategy can achieve go... |
