摘　　要：晶闸管在负载快速变化的过程中具有短时失控特性,输出电压容易波动。选取晶闸管整流电源作为研究对象,建立仿真模型,通过引入前馈控制器实现了对晶闸管整流电源输出电压的快速补偿,改善了电源的整体动态特性。通过仿真验证模型与控制器的有效性。研究表明,引入前馈控制器能够明显改善负载波动时整流电源的输出电压动态特性。The output voltage is easy to fluctuate due to the short-time out of control characteristics of thyristor in the process of rapid load change.The thyristor rectifier power supply is selected as the research object to establish the simulation model.The fast compensation of the output voltage of the thyristor rectifier power supply is realized by introducing the feedforward controller,and the overall dynamic characteristics of the power supply are improved.The effectiveness of the model and controller is verified by simulation.The study indicates that the introduction of feedforward controller can significantly improve the dynamic characteristics of the output voltage of rectifier power supply when the load fluctuates.
