welding regulator

A PI regulator with variable parameters is adopted for flexible and accurate current-waveform control, and the arc-voltage becomes robust against the variations of welding parameters.

本文采用变参数数字PI调节器，取得了好的脉冲电流波形控制效果，波形的一致性和可重复性好；弧压调节方法实现了在当前脉冲内即可控制弧压为给定电压。

A developed welder, which outputs corresponding secondary voltage by different combination of original side of tap voltage transformer and voltage regulator, can output appropriate welding voltage through 3 phases bridge silicon rectifier circuit.

所研制的CO2焊机是由抽头式变压器原边和电压调节器的不同组合输出相应的副边电压.通过三相桥式硅整流电路输出适当的焊接电压。
