A General Approach for Frequency-domain Design of Arc Welding Inverter

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。

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.
