针对逆变CO2焊机，设计了一种双闭环控制的电子电抗器。内环为电流负反馈，外环为电压负反馈，并分别设计相应的调节器来调节电流和电压，二者之间串级连接。实验表明，该电子电抗器控制的逆变CO2焊机波形调节性能好，不仅解决了物理电抗器体积笨重、不易调节的缺点，更有效地减小了焊接飞溅，改善了焊缝成形。

In this paper,designed a new electronic inductor which is double closed loop control for inverter CO2 welding.Inner loop was the feedback of current,outer loop was the feedback of voltage.An adjuster was designed to adjust current and voltage respectively, which connected each other in series.The experiment suggested this inverter CO2 welding supply controlled with electronic inductor has good capability of adjusting; little sputtering and fine weld formation.
