摘要: 提出了利用状态空间平均法建立弧焊逆变器小信号模型的一般方法,并根据自动控制理论的频域设计方法,利用该电路模型对恒流输出的手弧焊机进行设计,并给出相应的试验结果。

Abstract: This paper proposed a general approach to obtain a small-signal model of arc welding inverter by using the state-space averaging method.According to the frequency-domain design approach of classical control theory,a constant current output power for manual arc welding was designed based on the model,and experiment results were also given.
