| 摘 要： | 提高12脉波可控整流器谐波抑制能力，提出基于12脉波可控整流器的直流侧谐波抑制策略。该控制策略通过在直流侧附加谐波抑制模块，改善整流器输入电流波形，满足不同负载工况下输入电流谐波抑制要求；根据12脉波整流器交、直流侧电流关系和直流侧理想电流波形，分析并给出谐波抑制模块的输出电压波形，并采用全桥逆变电路调节谐波抑制模块的输出电压。仿真结果表明，该策略能有效抑制整流器输入电流谐波。

| Abstract: | n order to improve the harmonic suppression ability of 12 pulse controlled rectifier,the DC side harmonic suppression strategy based on 12 pulse controlled rectifier is proposed.The control strategy is expected to improve the input current waveform of the rectifier by adding a harmonic suppression module on the DC side to meet the requirements of harmonic suppression of input current under different load conditions.Based on the relationship between AC and DC sides of 12 pulse rectifier and the ideal waveform at DC side,this paper analyzes and gives the output voltage waveform of harmonic suppression module,and uses full bridge inverter circuit to adjust the output voltage of harmonic suppression module.Simulation results show that this method can effectively suppress the harmonics of rectifier input current. |
